Chinese universities have punished or removed several senior researchers after public allegations of data and image problems in high-profile biomedical papers. At the same time, the science blogger known as “Geng Tongxue” said Douyin permanently throttled his account and blocked commercial orders after he helped push those cases into public view. The university actions are supported by notices and mainstream reports. The Douyin claim rests on Geng’s own statement and later coverage, but the platform still has not publicly explained what happened.

## Summary

Among Teacher Li’s recent posts visible on a public mirror on June 1, the strongest verifiable news lead with high engagement was a repost about Geng Tongxue, a Chinese science blogger who said his Douyin account had been permanently throttled. The mirror showed 158 replies and 154 reposts on that item at the time of review.

The post mattered because it tied together two developments that can be checked separately. Several universities did take disciplinary action after allegations about manipulated research data and images. Geng also did say that one of China’s biggest short-video platforms had effectively cut off his traffic and monetization. What remains unclear is whether those two developments were directly connected.

## Confirmed facts

The broader misconduct story is real and on the record.

At Tongji University in Shanghai, an official university probe found problems in a 2025 Nature paper led by Wang Ping, then dean of the School of Life Sciences and Technology. South China Morning Post, citing Tongji’s official statement, reported that 14 of the paper’s 15 figures contained problems, including duplicated image data and faulty cell counts. Tongji removed Wang as dean, demoted him by two professional ranks, and imposed a 24-month ban on promotions, funding applications, and awards.

At Nankai University, the school first announced on May 1 that it had opened an investigation after online questions about a paper by a teacher surnamed Chen. By May 30, Xinhua reported that Nankai had terminated the contract of a postdoctoral fellow tied to the paper, removed one corresponding author from the dean’s post at the College of Life Sciences, and warned another corresponding author.

On the same day, Sun Yat-sen University announced penalties in a separate set of cases. Xinhua and China Daily both reported that the university removed two faculty members from leadership posts after finding image and data problems in their papers. China Daily said one researcher was removed from deputy director positions at two oncology research institutions, another lost a vice-dean post at the School of Life Sciences, and other people involved received penalties that included demotion, warnings, and temporary bans on project applications and graduate supervision.

State media did not treat Geng’s accusations as fringe gossip. On May 27, Xinhua published a feature on why his videos had drawn so much attention. It said universities had opened investigations and some accused scholars had already been punished. People’s Daily made a similar point and argued that the episode exposed weaknesses in China’s academic oversight system.

## What Geng said about Douyin

The platform restriction claim is narrower.

Geng said on May 29 that his Douyin account had been permanently throttled and that its Star Map commercial-order function had been permanently blocked. Lianhe Zaobao later reported the same claim and said Geng posted screenshots to support it. The report did not show a public response from Douyin explaining the restriction or identifying a rule violation.

That means the account restriction should be described carefully. It is reasonable to say Geng made the claim and that other media repeated it. It is not yet possible to say, based on public evidence alone, why Douyin acted, whether the restriction was platform-driven or ordered from above, or whether it was directly triggered by his academic-misconduct videos.

## Source verification

This article does not rely on the Teacher Li repost to prove the underlying story.

The university actions are supported by:

– Nankai University’s May 1 notice that it had opened an investigation.
– Xinhua’s May 30 English report summarizing disciplinary action at Nankai University and Sun Yat-sen University.
– China Daily’s May 30 report with more detail on the Sun Yat-sen penalties.
– South China Morning Post’s May 7 report on Tongji University’s punishment of Wang Ping.
– South China Morning Post’s May 31 report on further removals at Nankai University and Sun Yat-sen University.

The Douyin restriction claim is supported by:

– Geng’s own public statement as reported by Lianhe Zaobao.
– The Teacher Li repost, which is used only as a lead showing that the claim was spreading widely on X.

## Background

Geng’s rise was unusually fast because he turned a technical issue into something a mass audience could follow.

According to East is Read, Geng is a former doctoral student at Beihang University who turned to full-time science commentary after leaving his program. Between April and May, he publicly questioned papers involving scholars at Tongji University, Nankai University, Sun Yat-sen University, and other institutions. The newsletter said his Bilibili account had more than 1.8 million followers by mid-May, while his Douyin account had more than 1.3 million followers.

That reach helps explain why the story moved beyond specialist debate. Academic misconduct cases in China often stay inside journals, universities, and narrow online communities. This one moved into mainstream conversation because the allegations were presented in short, visual, easy-to-share videos, and because university punishments followed within weeks.

## Unverified claims

Several important points remain unverified.

One unresolved point is the exact status of Geng’s Douyin account inside the platform’s internal systems. Public reporting says he described the account as permanently throttled and commercially blocked, but there is no public platform notice explaining the reason.

Another is causality. It is possible that Douyin restricted the account because the videos created legal, political, or moderation risk. It is also possible that the restriction was tied to a rule that has not been disclosed publicly. The available evidence does not settle that question.

Scope is also unresolved. University statements and media reports confirm action in several cases, but they do not prove that all of Geng’s allegations against other scholars will be upheld.

## Potential impact

In the short term, the story adds pressure on universities to respond faster when prominent papers are challenged in public. It also raises a separate question for Chinese platforms. If a whistleblower can help trigger official investigations and still lose distribution on a major video app, others may think twice before pursuing similar cases in public.

For readers outside China, the episode is useful because it shows two systems operating at once. The academic system can still punish misconduct when the evidence becomes too visible to ignore. The information system can still narrow who gets to sustain that visibility.

## Information risk

The risk level is moderate.

The disciplinary actions at Tongji University, Nankai University, and Sun Yat-sen University are well supported by official notices and mainstream reporting. The uncertainty is concentrated in the Douyin part of the story. Until the platform explains the restriction, any claim about motive remains an inference.
