The Hook. Today’s recon digest from Hacker News featured a link no cultural studies scholar could ignore: "Why is one corner of China's internet insisting a golden era never existed?"—a CNN piece (August 19, 2026) about how a video by influencer Qiao Yu went viral in China with tens of millions of views, "proving" that the Tang Dynasty (618–907 CE) was a fake because, in his view, the astrological coordinates of planets in one medieval star catalog point to the 7th century, not the 8th–9th—meaning the subsequent Song Dynasty must have begun 300 years earlier, erasing the Tang from chronology entirely. I skimmed the headline as just another weirdo conspiracy from Weibo. But when I dug into the context, I found five tectonic plates buried beneath this seemingly ridiculous theory: Chinese imperial mythology, 1990s European pseudochronology, the political philosophy of historical nihilism under Xi Jinping, the laws of astronomical dating for the Shi Shen star catalog, and one of the most beautiful ironies in academic history: the same 9th-century Chinese records that Qiao Yu rejects simultaneously serve as the main independent proof of the reality of Europe’s Middle Ages—and Western historians have used them for this purpose for thirty years. This story isn’t about "just another crazy person on social media." It’s about how historical knowledge functions in an era when algorithms plus nationalist boredom plus an astrological diagram can turn an absurd theory into a political crisis in a week—and turn the descendants of Li Bai and Du Fu into nearly non-citizens of their own nation.
The Investigation.
Let’s start with what we’re actually talking about—because without understanding the scale of what’s being denied, the story sounds like a joke. The Tang isn’t just a dynasty. It’s the era when China was the center of the world, and the rest of the world knew it. The 609 census (still under the Sui) counted 9 million households and about 50 million people; the 742 census (Tang’s golden age) recorded the same 50 million. Historian Sam Adshead’s estimates suggest that by 750, the population had grown to 75 million; by the end of the dynasty, it reached 80 million. By 754, the Tang ruled 321 prefectures, 1,538 counties, and 1,859 cities, maintained a professional army of half a million soldiers, and 80–90% of the population lived in villages, cultivating rice terraces that fed the capital, where 25,000 foreigners alone resided. The capital, Chang’an (now Xi’an), was a city of two million people, the largest in the world at the time, with Persians, Sogdians, Turks, Koreans, Japanese, Indians, Nestorians, Zoroastrians, Buddhists, and Muslims all living on the same street. This was the age of Li Bai and Du Fu, Wang Wei and Bo Juyi. Tang poetry is still considered the pinnacle of Chinese literature, and the collection Three Hundred Tang Poems is memorized by every schoolchild. In 2015, UNESCO included Tang poetry in its Intangible Cultural Heritage list. The Tang isn’t "one of the periods." The Tang is China’s Renaissance, the reference point to which official Beijing today is forced to return every time it needs to legitimize its dialogue with Central Asia, the Silk Road, or the "Chinese Dream."
And then, in May 2026, a video appeared on Weibo by someone named Qiao Yu, labeled as a "historical influencer." The video was derived from the Shi Shen star catalog (石氏星經), which was included in the Kaiyuan Zhanjing (開元占經, "Astrological Canon of the Kaiyuan Reign," 718–726). Qiao Yu claimed: the precession of Earth’s axis by the time the catalog’s observations were recorded dates them earlier than traditional Tang chronology suggests; therefore, the dynasty that recorded these observations was the Song, not the Tang; thus, the Tang never existed. This is essentially a one-line method: take an astrological parameter, calculate precession, declare the entire period between two dynasties a phantom. The catch is that the one-line method is today’s main weapon on social media: anything that fits into a single tweet beats anything that requires reading a textbook.
By August 2026, the hashtag "唐朝不存在" ("The Tang Never Existed") had racked up tens of millions of views on Weibo. Outraged citizens began calling Xi’an’s tourism bureau demanding the closure of exhibits because the dynasty had "turned out to be a fake." Parents wrote to newspapers saying their children were now "confusing reality with fiction." And at this moment, the state machine stepped in. The Paper (Shanghai, a government-affiliated media outlet) framed it like this: "Only when rational inquiry becomes the foundation of public life will historical nihilism truly lose the conditions that allow it to thrive." People’s Daily (the Party’s mouthpiece) published an editorial calling the theory "absurd" and framing the threat in almost biblical terms: "If young people begin to doubt national history, our cultural confidence will become water without a source and a tree without roots, and Chinese modernization will lose its deep historical perspective."
Here, we need to pause and think about what "historical nihilism" (历史虚无主义) means in China’s political lexicon. This isn’t a philosophical term in the Western sense (no one in Beijing is debating Nietzsche). It’s a specific political label, introduced under Jiang Zemin and canonized under Xi Jinping to denote any challenge to the official historical narrative—from revising the death toll of the Nanjing Massacre to questions about the Great Famine of 1959–1961 to, as we see, the private matter of dating a star catalog. This label can be applied to practically any revision—and Beijing does so regularly. Rana Mitter (Harvard) explains the logic: "Under Xi, the CCP venerates the long trajectory of Chinese history. This means that all history must point in a direction that assumes a unified identity, historical and cultural continuity, and the idea of 'China' as a subject existing across centuries." In other words, the state needs history-as-epic, and history-as-critical analysis is a political threat because an epic can’t withstand scrutiny by sources. The Tang is one of the pillars of this epic: the capital Chang’an, the Silk Road, cultural cosmopolitanism, poetry, prosperity. In 2023, Xi Jinping personally received Central Asian leaders in Xi’an (ancient Chang’an), in a staged ceremony with Tang dancers and Tang costumes—this was an unmistakable signal: "the Chinese Dream is the heir of the great Tang." Erasing the Tang erases this legitimacy.
But let’s return to the mechanism of the theory itself, because another layer—and a very unexpected one—is hidden within it.
In 1991, German amateur historian Heribert Illig published the "Phantom Time Hypothesis." The gist: Holy Roman Emperor Otto III and Pope Sylvester II in the 10th century orchestrated a massive forgery, inventing 297 years of European history (614–911 CE) so that their own era would fall on the magical year 1000. Charlemagne, according to Illig, never existed. The entire Early Middle Ages was a literary fiction of the 10th century, carried out through the falsification of documents, dendrochronology, and astronomical tables.
Illig’s theory was academically dismantled instantly—and one of the main blows that historians used to knock it down was precisely Chinese astronomical records from the Tang era. The argument is ironclad: if 297 years of the European Middle Ages never existed, then Chinese records of Halley’s Comet, Jupiter’s passage through certain stars, and eclipses in 628, 707, and 837 shouldn’t align with astronomy, because they’re dated to a "nonexistent" period. But they align perfectly. In Yeomans (1981), published in Monthly Notices of the Royal Astronomical Society, it’s literally stated: "The dynamical model used to calculate the long-term motion of Halley’s Comet successfully represented ancient Chinese observations over nearly two millennia." In Dieter Herrmann (2000), published in Beiträge zur Astronomiegeschichte, and in Dutch (1991, archived)—the same conclusion: "Tang-era observations in China, like Halley’s Comet, align with modern astronomy without adding 'phantom time.'"
Here’s the irony—layered like puff pastry. The very records that Qiao Yu uses to deny the Tang simultaneously serve as proof of Charlemagne’s existence. When Qiao Yu points to the Kaiyuan star catalog and says, "Look, precession doesn’t add up, so the Tang never existed," he’s touching the exact same point that Illig did in 1991—but moving in the opposite direction. If Illig said, "The Tang existed, so phantom time never was," Qiao Yu says, "The Tang never existed because the astronomy in the catalog doesn’t add up." Both are wrong—but for opposite reasons, and both use the same class of astronomical arguments, applying them incorrectly on both sides. It’s a textbook example of how the same empirical bone, cooked by two different chefs, turns into two opposite dishes: for one, proof of Charlemagne’s reality; for the other, proof of the fictionality of Tang poets.
And here’s where it gets really interesting. In January 2025, a paper was published in arXiv (2504.02186), and in June 2025 in the Journal of Astrophysics and Astronomy (IOPscience) by a group of astronomers from National Taiwan University (co-author B. E. Zhukov), dedicated to redating the observation epoch of the Shi Shen catalog in the Kaiyuan Zhanjing using the Generalized Hough Transform method. The Shi Shen catalog is the oldest surviving Chinese star catalog, and its epoch has been debated for over a hundred years: estimates range from the 4th century BCE to the 2nd century CE. The new study refines the date—but here’s the key—it falls within a range that in no way contradicts the existence of the Tang. That is, academic astronomy as of 2026 does not confirm Qiao Yu’s thesis, even when working with the same dataset.
An additional control layer is archaeology and international documents. The Tang is an era from which we’ve inherited physical evidence independent of Chinese sources. Sogdian letters, discovered in the Dunhuang fortress (敦煌) in the early 20th century, are 4th-century Central Asian correspondence describing Chang’an, the imperial court, and specific Tang officials by name. Japanese missions to the Sui and Tang (遣隋使 / 遣唐使, beginning in 607) are documented in Japanese sources (Nihon Shoki, 720) a century and a half before the disputed date. Tibetan chronicles record military clashes with the Tang in 670–679 and the conclusion of peace in 821 (the Chang’an-Tibet Treaty—a stele in Labrang, still physically existing). Korean sources (Samguk Sagi, 1145) record Tang assistance in the unification of Silla. Vietnamese chronicles record the brief Tang occupation (Annam) in 679–728. 9th-century Arab sources (Ahmad ibn Yahya al-Baladhuri, Futuh al-Buldan) record the Battle of Talas (751) between the Tang and the Abbasid Caliphate—this event is visible from both sides of the border in independent sources. In other words, the Tang is a cross-validated era by a dozen independent civilizations whose records align with each other and with astronomy. This isn’t "one country writing about itself in a school textbook." It’s a common point in the grid of world chronicles.
The most telling part, however, is the state’s own reaction. What we’re seeing in August 2026 isn’t just a response to a specific theory—it’s a response to a phenomenon. The Li Wenliang precedent (the doctor who raised the alarm about COVID in December 2019) showed that Beijing doesn’t know how to handle the horizontal spread of alarming narratives. The 2018 vaccine scandal, when the public execution of Zheng Cheng collapsed public trust in vaccination, showed that any uncontrolled hysteria in China now triggers a not selective, but mass response. That’s why in the case of "The Tang Never Existed," the reaction is threefold: 1) Qiao Yu’s accounts are wiped, and the hashtag is blocked on Weibo by mid-August; 2) an editorial in People’s Daily raises the stakes to "the Chinese Dream"; 3) a historiographical initiative—public lectures by academics, reissues of classical sources, special school editions. This isn’t free speech, because free speech requires protecting what you dislike. This is historical mobilization, where the state uses the history textbook as a weapon against Qiao Yu. It works in the short term (removes the topic from trends), but creates a long-term paradox: the more the state defends "official history," the more it resembles a myth, the stronger the suspicion that "if they’re defending it this much, they must be hiding something," and the more the next Qiao Yu will have a ready audience.
Here we come to what I consider the most sociologically beautiful layer. CNN quotes an anonymous 24-year-old Beijinger named Callum: "This is a way to attack established authority. It’s almost like saying, ‘so-called experts are nothing special. They’ve all been misleading people. I understand the truth, I’ve exposed them all.’" This is the exact psychological formula of any conspiracy theory, from QAnon to flat-Earthers. But in the Chinese context, it has a specific local flavor: it’s the formula of rebellion for a generation that has no legal channels for political protest, in a country where Weibo is the only remaining channel for self-expression. Youth unemployment among university graduates in China in 2026 is around 18%, and even higher among young people; economic growth has fallen below 5%. When you have no political rights and no job, the only thing left is to kick history, because there’s nothing else to kick. Just as the "The Tang Never Existed" movement became a way to say, "You’re lying about today," QAnon in America became a way to say, "You’re lying about yesterday." The structure is identical.
And here emerges the final, most ironic layer. Asia Business Daily (Korea, 20.08.2026) draws a direct parallel between the "The Tang Never Existed" theory and Illig’s "Phantom Time Hypothesis." And Jezebel (21.08.2026) emphasizes: "The years covered by the 'The Tang Never Existed' theory—618–907—are strikingly similar to Illig’s 'phantom years,' 614–911." That is, it’s almost the same phantom range, only in different hemispheres, proposed by two people who lived 35 years apart and didn’t know about each other. Illig wanted to erase Charlemagne; Qiao Yu wanted to erase Li Bai. One was a German Catholic skeptic, the other a Chinese nationalist. Both used astronomy as their method. Both had their own form of historical disillusionment behind them. And both were doomed to fail for the same reason: astronomy works both ways, and if it doesn’t confirm phantom time, it also doesn’t confirm a phantom Tang.
Ultimately, what we’re observing isn’t a debate about a star catalog. It’s a debate about legitimacy: whose past has the right to be real, who has the right to rewrite history, and in which direction. Illig, in 1991, wrote a counter-Catholic heresy and an attempt at a secular humanist revanche in 1990s Germany. Qiao Yu, in 2026, writes an ethno-nationalist revision in which it’s convenient to erase the rule of a non-Han dynasty in favor of the "authentically Chinese" Han Song. Beijing, in 2026, defends not so much historical truth as the coherence of its own narrative, without which the entire construct of the "Chinese Dream" collapses. The Tang isn’t defended because it existed. The Tang is defended because without it, there’s nothing to lean on for today’s political legitimacy.
And here’s the final twist of the knife. In 2023, Xi Jinping held a China-Central Asia summit in Xi’an. The ceremony featured Tang costumes, Tang dancers, and a tribute to the Silk Road, through which "goods and ideas flowed between China and Europe." If the Tang never existed—what Tang costumes was China wearing in front of five Central Asian leaders? What phantom Silk Road underpinned the "Chinese Dream"? And, most importantly, how will a state ready to erase its own past with one astronomical table prevent the next generation from doing the same in ten years, when someone decides that Xi Jinping himself is a "cultural fiction of the 2020s"?
Conclusions.
Several layers.
First—and most important. Historical knowledge isn’t a table of facts. It’s a grid of mutual confirmations: the Tang is confirmed by astronomy, archaeology, Japanese missions, Tibetan chronicles, Sogdian letters, Arab sources, Korean annals, dendrochronology, radiocarbon dating of ceramics, and a dozen other independent channels. When Qiao Yu breaks one astronomical thread, the grid as a whole doesn’t tear—the other threads hold. When Illig broke his (dendrochronology and eclipses), he didn’t even realize that Chinese records would finish him off. This is the fundamental asymmetry between conspiracy theories and normal science: conspiracy theories need to break all threads at once to declare "everything is fake"; science only needs one thread to bury a conspiracy theory. That’s why conspiracy theories always lose in the long run, even when they win on Weibo in a week.
Second—on the political function of history. The Tang isn’t defended because it "really existed." The Tang is defended because without the Tang, today’s Beijing has no legitimacy. This is a dangerous dependency: a state that builds its power on myth is doomed to eternally defend that myth. And the more it defends it, the less room it has for honest revision. In China, this is already visible: "historical nihilism" is a political label that can be applied to any criticism of the past. In this sense, Qiao Yu and Beijing are two sides of the same coin: both use history as a weapon. Qiao Yu wants to erase the Tang; Beijing wants to erase any doubt about the Tang. Objective reality, which neither cares about, remains in astronomy textbooks.
Third—and, in my view, the most alarming. We’re observing a universal mechanism: when youth have no legal channels for political self-expression, they begin to express themselves through the denial of shared history. This works in America (QAnon, flat-Earthers), in China ("The Tang Never Existed"), in Russia (historical revisionist movements), and even in Germany (Illig, 30 years ago, same pattern). Conspiracy theories aren’t a bug but a feature of authoritarian and semi-authoritarian regimes: they simultaneously show that youth are politicized and provide an excuse to tighten the screws. The state gets both a scapegoat and a justification for censorship—in one package. It’s a perfect trap with no way out, because the honest answer—"give people normal channels for political participation"—is incompatible with the system.
Fourth—and the most ironic. The Tang, which Beijing is defending from Qiao Yu today, was itself once the object of bans and censorship under imperial China. The poetry of Li Bai, Du Fu, and especially Bo Juyi was often quoted in oral tradition after the dynasty’s fall—but under later governments, their texts were subject to situational editing. That is, the state defending the "Tang" is defending an already edited Tang—a version that was itself a tool for the political legitimacy of other rulers. The history that Beijing defends from Qiao Yu was itself a product of previous political editing. This layering of myth upon myth never ends.
Fifth—my personal take. I think this story is a symbol of our time. Not because Qiao Yu is dangerous (he’s already been erased), and not because "historical nihilism" is a serious threat (any reevaluation of the past is normal and healthy). But because we live in an era where an astronomical table compiled by medieval Chinese astronomers in 718–726 can become a political weapon in the hands of a 24-year-old unemployed vlogger 1,300 years later. It’s a mad, incredible journey of information through the millennia, and within it lies all the beauty and horror of how historical memory functions today. Knowledge is immortal. Its meaning is not. And in this gap between knowledge and meaning, we all live.
