Death of Yu Menglong

On September 11, 2025, Chinese actor Yu Menglong (Alan Yu) passed away at the age of 37 after falling from a residential building in Chaoyang, Beijing. His management team confirmed the news of his death later that evening on Weibo. The incident attracted widespread attention, and speculation about the cause of his death grew as unverified rumors spread online. On September 16th and 21st, Yu Menglong's family and the Beijing police respectively announced that his death was an "accidental fall caused by intoxication," but detailed case information remains unreported. Meanwhile, several Chinese social platforms restricted related topics, and the police announced that multiple "rumor spreaders" have been punished. However, public skepticism has not subsided, and the matter has evolved into a broader controversy over "unspoken rules" in mainland China's entertainment industry and restrictions on free expression. ^[1][2][3][4]

Background

Chinese actor Yu Menglong was found dead on the morning of September 11. According to multiple media reports, an eyewitness stated that around 6 a.m., someone was discovered lying beneath the residential building, bleeding from the mouth and nose, with visible bloodstains at the scene. Police and paramedics later arrived to handle the situation. That afternoon, reporters from Yangtze Evening News visited the building and noted that the window screen of the apartment involved was damaged, though it remained unclear whether this was accidental or intentional.^[5] Later that evening, Yu Menglong's management team released an obituary on Weibo, stating that police had ruled out the possibility of homicide.^[6]

Following the news of his death, large amounts of speculation spread online. Many netizens questioned whether his death was simply accidental, with rumors involving the entertainment industry's "hidden rules," suppression by powerful figures, and even claims of a "red USB" and abuse before his death.^[1][2][7] Chinese writer Luban and some netizens listed "suspicious points," suggesting the possibility of homicide^[7][8]; others questioned the suicide theory, claiming Yu Menglong's fear of heights made it unlikely he would end his life this way^[9][10]. Authorities and police later issued statements debunking the rumors, asserting that after on-site investigation, forensic examination, interviews, and review of surveillance footage, criminal suspicion was ruled out, and the family raised no objections.^[2][11] However, the public criticized the announcement as overly brief and lacking detailed evidence, fueling ongoing conspiracy theories.^[1]

As the public raises concerns, authorities launched the "Clean Net" campaign. Police took legal action against individuals who fabricated rumors, with several placed under compulsory measures.^[11] Platforms including Sina Weibo, Kuaishou, Toutiao, and UC Browser were summoned for talks and subsequently deleted or blocked large volumes of related content.^[12][13][14] Weibo also enforced a large-scale removal of fan community content, with many memorial posts disappearing. "Yu Menglong" became a sensitive keyword, prompting fans to use substitutes such as "Little Fish" to bypass censorship.^[15] Some Chinese netizens turned to other platforms such as Facebook and Threads to continue discussions, where the focus gradually shifted from the cause of death to wider dissatisfaction with authority figures.^[1]
