In the first half of 2019, the personal information of Xi Jinping's daughter and her brother-in-law were published on the Chinese websites "Hong'an Foundation" and "Zina Weiqi" outside China. The "Vulgar Vichy" website, which has a friendly connection with "China Vichy" and operates in China, was immediately targeted by the Chinese authorities, resulting in the arrest and punishment of 24 teenagers. Among them, Niu Tengyu, an operation and maintenance member of the "Vulgar Vichy" who went to Hong Kong to watch the anti-extradition movement in June 2019, was criminally detained by the Maoming police in Guangdong in August of the same year. He was arrested in September and tortured.
