Yu Menglong’s death case takes massive turn: Public outrage spills from social media to streets, actor's agency Tianyu Media faces big blow; here’s what you need to know

The outrage triggered by the death of Chinese actor Yu Menglong, also known as Alan Yu, took a massive turn when it entered the streets from social media. The 37-year-old actor died after falling from a building in Beijing on September 10, 2025. He was reportedly intoxicated at the time of the fatal incident. His death was confirmed by authorities, his agency Tianyu Media, and his mother.

Despite all the claims, multiple audios and videos circulated across social media suggesting that his death was not accidental and he was allegedly tortured and killed. Some purported audios and videos even suggested that the actor was beaten and tortured during a party on the night of his fatal death.

Alan Yu’s mysterious death has continued to ignite international outrage and calls for accountability. According to Vision Time, his death has prompted millions of fans to boycott concerts, television shows, and brands tied to Yu’s case.


Authorities ruled out foul play, but the claims have not been able to convince Chinese netizens, who have flooded the Chaoyang Police hotline requesting a formal investigation. The requests have met with constant refusals by Chinese police.

Yu Menglong’s death case fuels street protests

The movement, which flooded social media across China, has now entered the streets. According to the YouTube channel “Finance Cold Eye,” citizens have started taking to the streets to protest against “Tianyu Media,” chanting slogans like “Tianyu Media—shut it down!,” as reported by The Vision Times.

According to the online news platform, a large LED screen at the entrance of Wuyue Plaza in Jiangsu played close-ups of Yu Menglong on loop, accompanied by the text “I am Yu Menglong” on October 8, 2025.” Several users on Bilibili reported similar displays in several other cities, with comments reading, “We’re here on Oct 8—never abandon, never yield.” “One group, one cause. Together we fight, together we win.”

Tianyu Media and Mango Super Media’s stocks plummet, executives resign

Trouble mounted for “Tianyu Media,” Yu’s management company, and its parent firm, “Mango TV/Mango Super Media,” as it saw stock prices crash and several executives abruptly resign.

Following the public backlash, “Tianyu Media” and “Mango Super Media” suffered steep sell-offs. According to “Sina Finance,” Mango’s stock price plunged 6.68 percent on October 9 and another 5.12 percent on October 10, wiping out more than ¥7.67 billion RMB (over USD $1 billion) in market value in just two days, as reported by The Vision Times.

This comes days after it was revealed that Tianyu Media’s management and at least nine other artists have reportedly “died or disappeared” under suspicious circumstances as well. Many now believe Yu’s case is linked to the same corporate network and are uniting in a digital resistance movement targeting the firms and figures involved.

Mango Super Media’s own filings show that as of September 30, 2025, the number of shareholders had dropped to 37,900, down 15,400 from the previous month, a staggering 28.9 percent decline.

The declining trust of shareholders prompted resignations from executives. The company announced that Vice President Luo Zejun had formally stepped down and would no longer hold any position. Previously, Shen Yadong, vice president and general manager of Tianyu Media since 2020, also resigned, citing “personal reasons.”
