On November 23, Chan Chan CEO Zhao Changpeng said on Twitter that he would sue the blockchain media The Block. It is reported that The Block said in a report released on November 21 that the bank's office in Shanghai was closed after a police raid. According to sources, the office has a lot of management personnel and about 50 to 100 employees. The report was denied by the currency: "The currency security has no fixed office in Shanghai/China, so it is impossible for police to raided and shut down the office." At the same time, Zhao Changpeng also strongly opposed the factual accuracy of the article. And asked The Block to apologize. At present, The Block has replaced the word “police raid” in the title of the article with “authority visit”, and The Block has issued follow-up articles to defend its position, arguing that Zhao Changpeng’s “Kuan’an has not been established in Shanghai since 2017. The statement is inaccurate. Multiple sources and public information show that in the past two years, the company has two offices in Shanghai.
