We'll Use His English Name
On a smoggy August morning in 2009, outside the China World Hotel in Beijing, a crowd of teenagers and twentysomethings was being organized into a fan club. They held placards studded with LEDs. A wrangler moving among them had one instruction that mattered, and he shouted it over the noise: "We'll use his English name, okay?" A black Mercedes-Benz pulled up. The door opened. A boyishly handsome executive, forty years old and weeks short of forty-one, stepped onto the pavement. The crowd did as it had been told.
"Ro-bin! Ro-bin!"
The man they were screaming for was born Li Yanhong, the fourth child and only son of two factory workers in a coal city in Shanxi province. The name the crowd was told to use he had carried home from America, where he spent most of the 1990s writing software for Dow Jones and Disney and inventing, in a New Jersey office, one of the foundational ideas of web search. A few hours after the Mercedes arrived, at the company's annual Baidu World conference, Robin Li told an audience of thousands that the search engine he had built a decade earlier was becoming China's gateway to the world of information. Then he walked across the stage surrounded by smiling children while "Twinkle, Twinkle, Little Star" played in Mandarin and soap bubbles drifted through the hall.
Forbes, which was there to watch, called it Olympic-style marketing and did not say whether the young people on the sidewalk had been paid. Two years later Vanity Fair, compiling its annual list of the New Establishment, settled the matter in a single dry line filed under the heading "Evidence of Possibly Megalomaniacal Behavior": "Li has hired 'fans' to mob him at public appearances."
It is worth staying with that wrangler for a moment, because the instruction he gave holds most of what is strange and interesting about the man. We'll use his English name. Not his Chinese name, in Beijing, at a Chinese company's conference, before a Chinese crowd. The English name, the American name, the name that signaled Stanford lecterns and Nasdaq tickers and Silicon Valley picnics. In 2009 that name was the brand. Li's company was then known, to the point of cliché, as "China's Google." It had a market value of $12.8 billion and 7,000 employees, and it handled 8 billion searches a month for a country of 338 million internet users. Li's personal stake was worth around $2 billion. The year before he had been the seventh-richest person in China.
In a no-frills conference room afterward, Li told Forbes the sentence he seemed to want remembered. "A lot of Chinese people have wondered if knowledge really means power in today's market economy," he said. "I think I've proven that it does." By the end of that year the company would move into a new headquarters designed to look like an enormous rectangular search box, a building whose shape asks a question it cannot answer by itself.
What follows is an attempt to read the man the way his own algorithm reads a webpage: not by what he declares about himself, but by what points to him, from where, and with how much weight.

The Dimmest Candlelight
The company's name comes from a poem eight centuries old. Xin Qiji, a Song dynasty poet, wrote a lyric about the Lantern Festival called "Green Jade Table," and its last line is among the most quoted in classical Chinese: Having searched for her a hundred times in the crowd, suddenly turning back, she is there in the dimmest candlelight. "A hundred times" is bai du. Baidu.
The choice tells you something about the man who made it. Silicon Valley named its search companies after cartoon exclamations and misspelled numbers: Yahoo!, Google. Li reached for a twelfth-century poem about longing, a poem whose point is that the thing you have been looking for everywhere was behind you the whole time, in the place with the least light. A page later maintained under the RankDex name glosses the name as "a persistent search for the ideal." That is the corporate reading. The poem is lonelier than that. It is about a man in a festival crowd, among thousands of lanterns, who finds what he wants only when he stops looking forward.
Yangquan, where Li was born on November 17, 1968, is not a place associated with poetry. It is a mining and industrial city in Shanxi, the coal province, and Li grew up there during the Cultural Revolution, the fourth of five children and the only boy, his parents both factory workers. The official biographies, in the way of official biographies, describe an ordinary family. One detail survives that does not fit the arc of the dutiful scholar. As a boy, the English-language entry in his company's encyclopedia records, Li "was fascinated by Chinese opera and was admitted to the Shanxi Yangquan Jin Opera Troupe." Jin opera is the regional form, loud and stylized and Shanxi to the bone. The entry adds that during high school Li "refocused on his 'main studies,'" the quotation marks gently signaling that the opera had been a detour from the road a boy like him was supposed to walk.
He walked it. He got into Yangquan First High School with the second-highest score on the entrance exam, took computer classes, and entered programming competitions across the city. In 1987 he sat the national university entrance examination, the gaokao, and posted the top score in Yangquan. He chose Peking University and a major then called library and information science, later renamed information management, which is to say he studied cataloguing: how collections are ordered, indexed, and retrieved. It is hard to think of a better apprenticeship for a man who would spend his life ranking things.
Peking University sits in Haidian, next to the stretch of Beijing called Zhongguancun, which in the late 1980s was an electronics market crowded with stalls and early hardware merchants. Speaking at the university's 120th anniversary in 2018, Li recalled what caught his eye there. "I started to pay attention to people with beepers in Zhongguancun," he said. "I began to learn that messages could instantly send information to the other side of the ocean." These, he said, "were the ideal starting points for my further studies and entrepreneurship." The image is small and exact: a student from a coal town watching men in a street market receive signals from across the Pacific, and working out that the gap between here and there could be closed by a device on a belt.
From his junior year, by his own account, he set his sights on the United States and on computer science. He graduated in 1991. Two decades later he and his wife, Ma Dongmin, who goes by Melissa in English, would give RMB 660 million, roughly $104 million, to the university together with Baidu, for a fund supporting research compatible with Baidu's AI work. The beepers of Zhongguancun turned out to be worth a great deal of money.
Link Analysis, or the Logic of Reputation
In the fall of 1991, Li Yanhong arrived at the State University of New York at Buffalo to work toward a doctorate in computer science. Buffalo is a long way from Yangquan, though the two cities have more in common than either would admit: both industrial, both cold, both built on heavy things pulled from the earth and both a little behind the times. After a year Li won a three-month internship at Matsushita, the Japanese electronics giant now called Panasonic, an experience he later described, in a sentence his company's encyclopedia preserves only up to its first clause, as having "played a crucial role in my" (the rest of the thought lies past the edge of the available excerpt). By 1994 he had decided against finishing the PhD. He left Buffalo with a master's degree.
That May he took a job at IDD Information Services, a New Jersey division of Dow Jones & Company, where he helped build software for the online edition of The Wall Street Journal, a real-time financial information system for a newspaper just beginning to imagine life on a screen. He also worked, on the side and then not so much on the side, on how search engines should decide what to show first.
The search engines of the mid-1990s mostly judged a page by its own contents: how often a word appeared, where, in what font. That made them easy to fool, because a page could simply say what it wanted to be found for. Li's insight was that a page's own words were testimony and testimony is cheap. What mattered was what other pages said about it, and specifically whether they linked to it. A hyperlink was a vote. A page that many others pointed to was probably important; a page pointed to by important pages was probably more important still. He called it "link analysis." In 1996 he built a site-scoring algorithm and a search engine around it, RankDex, the first search engine to use hyperlinks to measure the quality of the sites it indexed.
On February 5, 1997, he filed for a patent titled "Hypertext document retrieval system and method." It issued on July 6, 1999, as U.S. Patent 5,920,859, inventor Yanhong Li. In the July/August 1998 issue of IEEE Internet Computing, he published a paper with a title that reads now almost like a manifesto: "Toward a Qualitative Search Engine." When Larry Page filed his own patent for a link-based ranking method, the system that became PageRank and Google, it cited Li's work.
The priority dispute, if it is one, is less interesting than the worldview the algorithm encodes. Link analysis is a theory of reputation. It holds that you cannot know what something is by listening to it describe itself; you know it by who vouches for it, and by who vouches for them. It is an epistemology of networks and endorsements, which happens to be a fairly good description of how influence works in a one-party state, and of how a young man from a coal town without connections might eventually be judged by investors who had never heard of him. Li would live inside that logic for the rest of his career, as both its beneficiary and its subject.
He left IDD in June 1997 for Infoseek, one of the pioneering search companies, as a staff engineer. Among his accomplishments there was the picture-search function used by Go.com, the portal Disney built after taking a stake in Infoseek. It was the Disney stake that soured things. Disney's commitment to search faded, and its attention drifted toward content and the logic of a media company. Li's did not drift. He was, by every account, frustrated.
In the summer of 1998, at a picnic in Silicon Valley, a friend named Eric Xu introduced him to someone who might understand. Xu was 34, a biochemist with a doctorate and, more usefully, good contacts across the Valley, and he was making a documentary about the place. He had gathered some friends together for it and thought two search people might get along. One was Li, then 30, whom Xu's acquaintances remembered as shy and reserved. The other was John Wu, who ran the search engine team at Yahoo, the most important internet company in the world at the time and one that, Wu admitted later, had decided search was not where the action was. Yahoo would eventually outsource its search entirely to a small start-up called Google, a decision the New York Times would describe as a colossal corporate blunder.
Wu later moved to China himself, as chief technology officer at Alibaba.com, which gives his memory of the picnic a certain retrospective ruefulness.
The people at Yahoo didn't think search was all that important, and so neither did I. But Robin, he seemed very determined to stick with it. And you have to admire what he accomplished.
— John Wu, former head of Yahoo's search engine team, recalling the 1998 picnic where he met Li
The shy man at the picnic, quietly refusing to give up on the unfashionable thing. Hold onto that image. It will come back, in less flattering lighting.
The Third-Best Search Engineer in the World
There is a story, told in the Chinese book
Robin Li, Baidu World, that has the tidy shape of a corporate parable and a few details odd enough to suggest it is at least partly true.
Li and Xu were raising seed money. One of the prospective investors was Scott Walchek of Integrity Partners. During the meeting Walchek asked the young engineer across from him a question he presumably already had an answer to: who were the top three people in the world in search engine technology? Li named two men, identified in the book only as Mr. X and Mr. Y, and then a third: William Chang, chief technology officer of Infoseek, his own boss's boss. He did not name himself.
Walchek excused himself, stepped out of the room, and phoned William Chang, whom he knew. Was this Robin Li really that good? Chang's answer, as the book tells it: in search engine technology, Robin Li ranks in the top three in the world.
Walchek came back in, according to the account, and raised his offer. Integrity Partners and the second investor would put in $1.2 million instead of $1 million, split fifty-fifty. The second investor, per the New York Times, was Peninsula Capital.
Read as parable, it is about modesty, the book's author attributing Li's omission to "Eastern humility." Read through the logic of RankDex, it is about something else entirely. Li did not rank himself. He let a link do the work. The investor checked the inbound reference, found it came from a highly ranked node, and repriced the asset upward by 20 percent within the span of a phone call. Whether Li understood this as a tactic or simply as manners, the result was the same: his first fundraise was decided by the algorithm he had patented.
The name William Chang will come up again, attached to a Baidu executive speaking at a conference in 2008. The sources do not say plainly whether it is the same man. It is that kind of story, full of names that circle back.
Walchek, for his part, was candid about what he had not understood. "We were skeptical about search," he told the Times years later, by then on Baidu's board. "But we weren't as smart as Robin. Robin said he had a unique opportunity to build a brand around search. And he was right."
With the money in hand, Li and Xu flew to Beijing. They set up in a hotel room overlooking the Peking University campus, the same campus where Li had once watched the men with beepers. Baidu was incorporated on January 18, 2000. That September, as the dot-com bubble began to burst in America, Draper Fisher Jurvetson and IDG Technology Venture put in another $10 million. "So it was," the Times wrote, "that on the eve of the Internet bubble bursting in the United States, Baidu took off in China."
The early business was not glamorous. "We didn't have a feasible business model, let's put it this way," Li said later. "When we started, the business model is to provide the backend search technology to the portal companies in China." They built a strong Chinese-language engine and signed up, in short order, nearly every portal of consequence: Sina, Sohu, NetEase, Yahoo! China. Baidu was the plumbing behind other people's storefronts, invisible and paid accordingly.
Recruiting was a matter of belief more than money. In a letter to staff written sixteen years later, in the worst week of his professional life, Li recalled those days with an intensity that cuts through even a rough translation. Google, he wrote, could pay three times what Baidu could. People stayed anyway. To find them, the company made posters pairing famous faces with short appeals: the writer Lu Xun for those who wanted to make search meaningful for Chinese people; the rocket scientist Qian Xuesen, who returned from America to found China's missile program, for engineers; Mao Zedong over a line asking, more or less, whether you would surrender or become stronger than your enemy. Even now, Li wrote, when he repeated those slogans to people, they got choked up.
Lu Xun, Qian Xuesen, Mao. A writer, a returnee, a revolutionary. It is a revealing trinity for a company founded by a man fresh off seven years in America with an English first name and a U.S. patent. The posters announce what Baidu was selling to its first employees: not stock options so much as a homecoming.
A Brand Built Around Search
Somewhere in 2000 or 2001, Li noticed what a company in Pasadena called Overture was doing. Overture sold advertising alongside search results and auctioned the slots, so that, in the Times's example, ads for dental clinics would appear beside results for "cavities." The insight was that a search query is the purest statement of commercial intent ever invented: someone typing "cavities" is, at some level, asking to be sold a dentist.
Li moved fast. In 2001, Baidu let advertisers bid for placement and pay only when a user clicked, ahead of Google's own move to that model. The RankDex-branded "about" page, whatever its provenance, states the philosophy plainly: unlike Lycos and AltaVista, "which charge by flat fee," the products were "performance based." In September 2001, Baidu stopped being solely a back-end supplier and launched its own site, Baidu.com, with a homepage that looked almost exactly like Google's: a logo, a box, a button.
Small and medium-size Chinese businesses loved pay-for-performance advertising. Traffic poured in. In 2003 the company added news and picture search. In 2004 it turned a profit, and Li, who had been president and chairman since the founding, took the title of chief executive. He began pushing for an initial public offering in the United States, insisting, the Times reported, that it would be "a huge branding event."
He was right about that too. Baidu listed on Nasdaq on August 5, 2005, priced at $27 a share and structured, as Chinese internet companies are, through a variable interest entity incorporated in the Cayman Islands. By the close of trading it was at $122, up 354 percent, the biggest opening day on Nasdaq since the dot-com peak. Baidu was suddenly worth $4 billion and Li's shares more than $900 million. Many analysts called the stock absurdly overvalued, and it eventually slid to as low as $44 before recovering.
Before the IPO there had been a road not taken. Google had invested $5 million in Baidu early on and, according to Vanity Fair, came close to buying the company outright before it listed. Imagine the alternate history: Robin Li as a Google executive, Baidu as Google China, a single global search company with a Mandarin front end. It did not happen, and the reasons it did not are partly commercial and partly about everything else this profile is about.
The other thing critics noticed at the IPO was the advertising. A search on Baidu for the word "cancer," the Times reported, turned up ads for hospitals that had paid for top placement rather than information about cancer itself. Google and Yahoo put their ads in a column on the right; Baidu blended them into the results. Remember the word "cancer." It is the hinge of this story, and Baidu would be shown it many times.
By the following year Google had arrived in force, planning to spend hundreds of millions of dollars in China. Its China president, Kai-fu Lee, framed the contest as a matter of integrity. "People want information and they want global information," he said. "We can't be bought." The line was a direct shot at Baidu's paid rankings, and it carried the confidence of a company that believed the better product would win.
Analysts were less sure. "The globally dominant U.S. Internet companies have failed to take the No. 1 market share position in any category," Jason Brueschke of Citigroup said of China. "And they came with more money and major brand names. And so there's something fundamentally different about this market." Richard Ji of Morgan Stanley offered a demographic explanation: 70 percent of China's internet users were under 30, "most of them are single, only children. They're looking for entertainment." Baidu's MP3 search, which linked freely to music files and drew copyright lawsuits, was one of the things they were looking for.
Li's response to all of this was flat, almost stubbornly simple. "At the end of the day," he said, "if a user finds relevant information, they'll come back." And: "Our traffic keeps increasing. We're now the No. 1 Web site in China."
In December 2007, Baidu became the first Chinese company included in the Nasdaq-100. The shy man from the picnic now had a seat in the index of the American companies he had once worked for.
The Literal Cost
Baidu's dominance had a precondition that its founder rarely discussed in moral terms. Chinese censors oversaw the site; the government regularly blocked Google and imposed strict rules on foreign internet companies. The Times put the arrangement plainly in 2006: "In exchange for letting censors oversee its Web site, Baidu has sealed its dominance with support from the Chinese government." Documents leaked in April 2009 from Baidu's internal monitoring and censorship department showed long lists of blocked websites and forbidden topics. China Digital Times would describe the company as the most active and restrictive censor in search.
Li's way of talking about this was revealing in what it emphasized. In an interview with Bloomberg TV in August 2010, he described compliance not as a moral dilemma but as an expense. "We have to spend a lot of resources to make sure our content and services abide by Chinese law," he said, "and [Internet companies based outside China] don't." Gady Epstein of Forbes picked out the nuance: Li had raised "the literal financial cost, as opposed to what Google considers the moral cost." The man who had built a theory of search around measurable signals was treating censorship as a line item. Foreign Policy summarized the stance more bluntly the same week: Li, it said, "is said to have very cosmopolitan instincts in some regards, but has made the calculation that business in China requires being utterly apolitical — in other words, doing what the government requires you to do."
Apolitical is a generous word for some of what he said in public. Fortune in 2011 quoted Li's description of what made the Chinese internet strong: "walking the path of socialism with Chinese characteristics is the well-spring of strength that will allow the Chinese Internet to continue its healthy and rapid development." Fortune's writer called this rhetoric that might "veer precariously close to pandering," then added, with a straight face, that Li's job might be the hardest in the world.
The reason it might be became clear that August, when CCTV, the state broadcaster, aired a 26-minute documentary attacking Baidu. Millions of viewers watched a Baidu employee help a man posing as the owner of an admittedly fake healthcare company buy an advertisement for a phony weight-loss pill. Speculation ran for weeks: was the state uneasy with Baidu's 80 percent share of search? Was CCTV, which was building a search engine of its own, simply acting commercially? It was not the first round. In 2008, after an earlier skirmish between CCTV and Baidu, the company sponsored CCTV's 2009 Spring Festival Gala and increased its advertising spending by 41 percent, much of it flowing straight to the broadcaster. By the fall of 2011 a member of the Politburo had paid Baidu a highly public visit at a technology exhibition, the customary signal that a company was back in favor. Duncan Clark, chairman of the Beijing consultancy BDA China and one of the most experienced foreign observers of Chinese technology, read the whole episode as "more about control and economic interests than anything political."
The pattern is worth stating without decoration. Baidu sells attention. CCTV sells attention. The state owns one and licenses the other. When they collide, the private company pays, sometimes literally, with Spring Festival sponsorship money.
Google had already made its choice. In 2010 it moved its Chinese search service to Hong Kong, effectively leaving the mainland market. Publicly, Baidu played down its windfall. Privately, the numbers spoke: Baidu's share of China's search advertising market rose to about 70 percent, up six points in a single quarter. That same year a hijacker, posing as the "Iranian Cyber Army," talked a Register.com support worker into changing Baidu's domain email address and redirected Baidu.com for four hours. Baidu sued for negligence; Register.com apologized and settled. Even the company's worst day of 2010 was a dispute with an American vendor.
By 2011, Forbes estimated Li's fortune at $9.4 billion, which made him the richest man in mainland China. From 2013 to 2018 he sat on the National Committee of the Chinese People's Political Consultative Conference, the advisory body where the party gathers its approved non-party notables; he would also serve on the next one. He was a vice chairman of the All-China Federation of Industry and Commerce. On December 18, 2018, the Central Committee of the Communist Party and the State Council awarded him the Reform Pioneer medal. His official biography, in Chinese and English, describes him as a "non-party personage," a man outside the party and in no meaningful sense outside the system.
It was also in 2011 that the novelist and racing driver Han Han wrote Li an open letter. Han Han had just come back from a paper mill in Shandong where he and his publisher, Shen Haobo, had watched more than a million printed copies of the second issue of his magazine, Chorus, go into a pulping furnace along with industrial waste, three hundred-odd tons of paper. A few million yuan, he wrote, might be a small sum to Li; to a publisher it was a year's work wiped out. The letter was about Baidu Wenku, the company's document-sharing service, where Chinese writers' books circulated free. Its sharpest move was its framing. Here was a writer who had just lost a fortune to forces he did not name, addressing the richest man in the country, whose platform was taking the rest.
An Encyclopedia With Locked Doors
In 2005 the Chinese government blocked Wikipedia. Around April 20, 2006, Baidu released its own encyclopedia, Baidu Baike, created by Li and modeled closely on the thing that had just disappeared. Within twenty days it had more than 300,000 registered users and more than 100,000 articles, more than the Chinese-language Wikipedia had accumulated. Two years later, at the World Wide Web Consortium's WWW2008 conference, a Baidu executive named William Chang gave the most succinct justification anyone has offered. "There is, in fact, no reason for China to use Wikipedia," he said. "It's very natural for China to make its own products."
Baike is the clearest window into how Li built things, because it shows every tendency at once: the speed, the scale, the substitution, the integration, the commercial instinct, and the political ceiling.
Speed and scale first. By 2025 Baike claimed more than 30 million entries and some 8 million editors, the largest Chinese-language encyclopedia anywhere. Integration: when a Baidu search matches a Baike entry, the link to that entry usually appears at or near the top. The rival encyclopedia Hudong complained about precisely this; in 2010 its chief, Pan Haidong, posted "Three Questions to Robin Li" on Weibo, challenging the ranking Baidu gave its own services. Baidu sued him and won. A court ordered Pan to pay Baidu 120,000 yuan.
Substitution has costs. In 2007 Florence Devouard, then chair of the Wikimedia Foundation, said of Baike: "They do not respect the license at all... That might be the biggest copyright violation we have. We have others." Chinese Wikipedia editors compiled lists of allegedly copied entries; Wikimedia declined to sue. And then, almost two decades later, the story turned on itself. In 2025 a Beijing court found Douyin Baike, ByteDance's encyclopedia (formerly Hudong, which ByteDance had bought), guilty of illegally copying 600,000 Baike entries and faking user data to make it look like ordinary editors had done it. Damages: 8 million yuan. The encyclopedia once called the biggest copyright violator on the internet had become a victim of copying, and a court upheld its claim.
The commercial instinct showed up in small details. Editors earned "gift points" for edits, redeemable for snacks and stationery and, at the high end, refrigerators, washing machines and smartphones, a reward system that one researcher argued encouraged volume over quality. By 2016 nearly 100,000 physical Baike QR codes had been placed at more than 200 locations across China, linking temples and buildings to their entries. In 2015 Baidu launched "Baike Youming," a paid service letting entrepreneurs and artists control their own biographies. Businesses complained of being steered toward a 6,000-yuan-a-year enterprise package to speed up corrections. The encyclopedia does not accept edits between 11 p.m. and 8:30 a.m. Beijing time, ostensibly for the health of its volunteers, plausibly for the convenience of its auditors.
Then the political ceiling. All editors register under their real names; administrators review every edit before it appears. As of 2013, a scholar reported, entries about senior Chinese leaders were fully locked, as were the entries about Baidu itself and its CEO, Robin Li. Articles on the 1989 Tiananmen Square protests did not exist. In 2009, users invented the "Baidu 10 Mythical Creatures," fictional animals whose names sounded like obscenities, most famously the Grass Mud Horse, cao ni ma, a near-homophone for a crude insult. The Grass Mud Horse became a mascot of evasion across the Chinese internet. It was born inside Li's encyclopedia.
Here is the shape of it. A man whose great invention was the idea that a page's value comes from what others say about it built the largest encyclopedia in his language, then arranged for the page about himself to be locked against what others might say.
A decade after Baike's launch, the same integrations had turned on the company's main product. In January 2019, Fang Kecheng, a communications scholar, published a viral post declaring the Baidu search engine dead. "Baidu.com is no longer a place for you to search for content on China's internet," he wrote, "but rather an internal search for Baidu content... It won't lead you to good quality food for the spirit from China's internet, but content hoarded at home, gone bad." Part of the blame belonged to rivals who refused to let Baidu index their walled gardens; part of it, critics said, belonged to Baidu, which kept surfacing low-quality posts from its own blogging platform, Baijiahao. The poem behind the company's name is about searching a crowd and finding the one person who matters. By 2019, the crowd had been fenced off and the search engine was mostly finding itself.
Thirty Days
Wei Zexi was a computer science student at Xidian University in Xi'an. In his teens he was diagnosed with synovial sarcoma, a rare cancer of the soft tissue. He and his family searched Baidu for treatment. Near the top of the results was the Second Hospital of the Beijing Armed Police Corps, promoting an experimental immunotherapy. The family spent around 200,000 yuan, about $31,000, on the treatment. It failed. Before he died, Wei publicly accused the hospital of misleading his family and criticized Baidu for selling medical search listings to the highest bidder. He died on April 12, 2016. He was 21.
His death spread across the Chinese internet in a way few corporate scandals had. One report claimed medical advertising made up as much as 30 percent of Baidu's ad revenue, much of it from for-profit hospitals in the so-called Putian network, founded by entrepreneurs from one region of Fujian province. On May 2, the Cyberspace Administration of China sent investigators to Baidu. Within a week, a joint task force concluded that paid listings had compromised the objectivity of Baidu's results, that the company favored high bidders and failed to label sponsored links. Regulators ordered it to stop ranking results by payment, to add risk warnings, and to limit paid results to less than 30 percent of each page. Baidu's shares fell 12 percent over the month.
It is worth pausing on the chronology, because the chronology is the indictment. In 2005, the Times noted that a Baidu search for "cancer" returned paid hospital ads instead of information. In 2009, Li told Forbes he would overhaul the ad system, under a project code-named Phoenix Nest, to separate paid results clearly from organic ones. "Even if this means we have to suffer for a few quarters," he said then, "I'm willing to make that bet — or sacrifice — to make sure we're moving in this direction. It's not an easy decision for a CEO. But if we imagine the company ten years down the road, it's an obvious one." In 2011, CCTV showed a Baidu employee helping a fake company buy an ad for a fake pill. In 2014, Baidu began selling moderator rights to forums on Tieba, its message-board network. In January 2016, a Tieba forum devoted to hemophilia was sold to a hospital, which removed the volunteer moderators and deleted posts complaining about the change. A forum for Minecraft went to a knockoff mobile game for, according to one headline, 9.3 million yuan.
Bai du. A hundred times. The same lesson, relearned.
Li's response came as a letter to all employees, leaked within hours, and it is the most revealing document he has ever produced, because in it the man who usually spoke in stiff, measured English about traffic and execution sounds like someone who had been awake all night. He wrote of questions he had been asking himself "in the dead of night": "Why so many everyday Baidu users no longer love us? Where is the problem in the end?"
I see senior engineers trapped in a conflict of interest between commercial interest and user experience, and often compromising the latter.
— Robin Li, internal letter to Baidu staff, May 2016
He did not blame regulators, or rivals, or the hospital. He blamed the dashboard. "The management and employees' obsession of KPI," he wrote, "has twisted our values... and distanced ourselves from users." Departments quarreled over performance indicators; engineers compromised to hit commercial targets. Then came the sentence that became the headline in every outlet from People's Daily to the BBC: "If we lose the support of users, we lose hold of our values, and Baidu will truly go bankrupt in just 30 days."
He compared the reforms to cutting one's own wrist. He proposed a "one-vote veto" for user experience, overseen by a separate division with authority to kill any product that violated it. He announced a 1 billion yuan fund to compensate users harmed by misleading promotions. He told the BBC's readers, through the letter, that Baidu must put "values before profits."
The line about thirty days is a strange one when you look at it. Baidu was not going bankrupt in thirty days; it held most of China's search market and its users had nowhere obvious to go. The line was not a forecast. It was a scream meant to be heard on the floor, an attempt by the founder to reach past a layer of managers who had learned to read his priorities off a spreadsheet. A company organized around KPIs had optimized for exactly what its CEO had measured, and the CEO was now discovering, sixteen years in, that the measure had swallowed the mission.
Four years earlier, in November 2012, he had tried a different metaphor in a different memo. The company, he wrote then, had lost its "wolf spirit" and turned into something more like a panda, comfortable and complacent, grazing on its search monopoly. The commentator Doug Young, a former Reuters journalist, compared Baidu to Yahoo, the pioneer that coasted. In 2014 Baidu's search share had slid to 56.3 percent against Qihoo 360's 29 percent. The memos kept coming because the problems kept coming, and the problems kept coming partly because the memos did not change the incentives.
Baidu's net income fell from 33.7 billion yuan in 2015 to 11.6 billion in 2016.
The Main Course
If the Wei Zexi scandal marked the end of something, it also accelerated a turn already underway. On May 16, 2014, Baidu had named Andrew Ng, the Stanford researcher who had helped found Google's deep-learning effort, as chief scientist, to run Baidu Research out of new labs in Silicon Valley and Beijing. The company had already been folding deep learning into Phoenix Nest, the ad system, which is a small irony worth noting: the first serious AI at Baidu was put to work on the advertising.
In January 2017, Li overhauled his management team to refocus the company on artificial intelligence, and his wife, Melissa Ma, who had worked alongside him in the early years, returned to Baidu as a special assistant. That April he told CNN that AI was the new electricity. The same month Baidu announced Apollo, an open self-driving platform offering vehicle, hardware, software, and cloud components to the auto industry; by September there was a $1.5 billion fund to back up to 100 autonomous-driving projects over three years, alongside partnerships with Bosch and Continental. In November 2017 the first Baidu World under the new theme was titled "Bring AI to Life."
The state followed, or led; with Chinese technology companies it is often hard to tell which. In 2018 Beijing designated Baidu one of its national "AI champions." Time put Li on the cover of its Asia edition on January 19, 2018, under the word "innovator," the first Chinese internet entrepreneur to appear there. In September, at the Bloomberg Global Business Forum in New York, seated beside Christine Lagarde, he gave a line that sounded rehearsed and was clearly meant to travel.
If the internet was the appetizer, then AI is the main course. The internet changed a lot of our daily lives, but did not have much impact on the 2B industries. I think AI will change that.
— Robin Li, Bloomberg Global Business Forum, September 2018
Baidu's market value had touched $99 billion that May. In October, it became the first Chinese member of the Partnership on AI, the U.S.-based ethics consortium. That July Li had gone home, in a sense, giving a lecture on AI to nearly 500 students and faculty at Shanxi University in Taiyuan, which made him honorary president of its new big data academy.
Then came winter, which he named himself. In a New Year letter to staff on January 2, 2019, Li wrote that "winter is coming," and that economic restructuring was "as cold and real as winter to every company." He reached for an image from the Analects: "Only when the year grows cold do we see the qualities of the pine and the cypress." Revenue for 2018 had crossed 100 billion yuan. In April, BuzzFeed News reported that Android apps from DO Global, the overseas utility-app business Baidu had spun out the year before, had been secretly clicking ads in the background on users' phones; on April 26 Google banned DO Global and more than 100 of its apps from the Play Store. In May, Baidu reported its first quarterly loss since its IPO, 327 million yuan, about $47.5 million. Li wrote again. "For senior managers, saying 'I have tried' is not enough and we need to make sure we win in the battlegrounds that we must win." Net income for 2019 came in at 2.1 billion yuan, a sixteenth of what it had been four years earlier.
There is a pattern in the letters, and it has its own rhythm: a crisis, a memo, a metaphor drawn from nature (wolves, pandas, pines, winter), a demand for a change of spirit. The man who invented a ranking system based on external evidence keeps turning, under pressure, to the most internal tool a chief executive has: exhortation. It is not clear the letters ever worked. It is clear he kept writing them.
What he also kept doing was spending. Look at the composition of the revenue. In 2015, online marketing, the search ads and their relatives, brought in 64.0 billion yuan; everything else brought in 2.3 billion. By 2024, online marketing was 78.6 billion and everything else was 54.6 billion, a category that included iQIYI's video business, which Li chairs, and the cloud and AI work he had staked the company on. The ad engine had barely grown in a decade. The second business had grown more than twentyfold. It was paid for by the first.
In a speech at Baidu Create in early 2023, Li explained his theory of innovation with a thought experiment. Hand a blind person a scrambled Rubik's cube and ask them to solve it at one turn per second, he said, and it would take 137 billion years. Tell them after each turn whether they were getting closer or further away, and it would take two and a half minutes. "Innovation drives growth," he said, "feedback drives innovation." He predicted that smart transport would end the need for car-purchase and traffic restrictions in Chinese cities by 2027, and that traffic jams would be essentially gone by 2032.
The feedback arrived soon enough. On March 16, 2023, Baidu unveiled ERNIE Bot, its answer to ChatGPT. Li would later call it the first ChatGPT-like chatbot from any public company in the world. The planned public webcast was switched, at short notice, to a closed-door session with test customers; the public release came that August, Ernie 4.0 in October. By late 2024 Li was citing 300 million users. That September, Time put him on its inaugural list of the 100 most influential people in AI, the only Chinese entrepreneur included. At the World Artificial Intelligence Conference in Shanghai in July 2024, asked about the brutal discounting among Chinese model makers, he said what a veteran of the Chinese internet might be expected to say: "I think a price war is almost inevitable. Having been in the Chinese internet industry for so long, we are very familiar with price wars. It has come even earlier than I expected." He argued for closed-source models against open ones, and estimated that artificial general intelligence was more than ten years away, maybe twenty or more.
In January 2025 a small Chinese lab called DeepSeek released an open model that shook the industry. On March 16, 2025, exactly two years after ERNIE Bot's debut, Baidu released ERNIE 4.5 and a reasoning model, ERNIE X1, which it said matched DeepSeek's R1 at half the price. The champion of closed source was now pricing against an open-source upstart.
The cars did better. By April 2024 Apollo Go, Baidu's robotaxi service, had completed six million driverless rides in eleven cities, with more than 400 driverless vehicles in Wuhan alone. At the World Governments Summit in Dubai in February 2025, Li claimed the fleet had driven more than 130 million kilometers autonomously without a serious accident, that its insurance claims rate was one-fourteenth of an ordinary car's, that robotaxis were "at least 10 times safer" than human drivers. In late 2024 Baidu won Hong Kong's first pilot license for autonomous driving. In July 2025 it announced a partnership with Uber to deploy Apollo Go outside the U.S. and mainland China, the company whose founder had once named his engine after a Song poem now riding on the rails of the most American of platforms.
The machinery kept coming. In January 2026 Baidu filed to list its chip unit, Kunlunxin, in Hong Kong. In June 2026 the U.S. Department of Defense put Baidu on its list of "Chinese military companies." Revenue, meanwhile, had begun to slide quarter after quarter as advertising shrank faster than AI grew, and Reuters reported in 2026 that Li had vowed to return ERNIE to the frontier after months without a major upgrade.
His fortune had gone the same direction as the share price. A South China Morning Post profile in 2017 put his net worth at $20 billion. By May 2025, Forbes estimated $5.5 billion. He still holds about 18 percent of Baidu's equity and 59 percent of its votes, enough to keep making long bets whether or not the market agrees with them.
In May 2024 his head of communications, a vice president named Qu Jing, posted videos on Douyin defending punishing hours. In one she said she had asked an employee to take a fifty-day business trip during the pandemic, and observed that she was not the employee's mother. The backlash was immediate. She apologized and reportedly left the company. Baidu's Hong Kong shares fell 2.17 percent. A company founded on recruiting posters of Lu Xun and Mao, on engineers who stayed for a third of Google's pay, had produced a spokesperson who said aloud what the KPI letter had warned about in 2016.
Mr. AI
In October 2015, on the night Baidu's travel site Qunar announced its merger with its rival Ctrip, Li was not in a boardroom. He was at Fudan University in Shanghai, giving a talk. The host asked him to rate his life out of ten. He gave himself a ten. "I'm very optimistic about myself," he said. He rated his outfit that day a six, a pass, which in Baidu's engineering culture, the report noted, was about right.
The students had written him a song. It was called "Mr. Robin Li, I really want to meet you," and its lyrics, in a mix of Chinese and English, were tender and slightly absurd: Hi Robin, I've heard of you, the legendary idol is you; Hi Robin, where are you? Out past the Fifth Ring Road in Xi'erqi. Xi'erqi is the district in northwest Beijing where Baidu's search-box headquarters stands. Hi Robin, I can't forget you. Stay true to yourself; focus is the secret of all success.
Nobody had to tell these students which name to use. Six years after the wrangler outside the China World Hotel, the English name had become simply what you called him.
In February 2026, Baidu launched BaiduWiki, an international version of Baike in English, Japanese, French, Spanish and Russian, opening with more than a million articles translated from Chinese with the help of AI tools. The encyclopedia that began in 2006 as a replacement for a blocked Wikipedia was now being sent abroad in Wikipedia's own language. There is an entry for Li in it. Its summary reads, in the cadence of a personnel file: "Robin Li, male, Han ethnicity, non-party personage, born in November 1968 in Yangquan, Shanxi." Further down, it records the opera troupe. Under "Alias," it lists a name he did not grow up with and the students at Fudan never sang: Mr. AI.
No volunteer will edit that page, not in Chinese and probably not in English. No inbound link will move it. It sits at the top of the results when you search for him on his own engine, lit the way the company's founder once imagined the thing you are looking for would be lit, in the place you forgot to check. And across the top of it, above the Han ethnicity and the coal city and the boy who once trained for the stage, the machine has done without being asked what a man with a megaphone once had to tell a crowd to do.
It uses his English name.
