Hu Xiaowei and Chen Zhi have always called him "Big Brother," but his real name is actually Wu Anming. This person has a very strong anti-espionage awareness, and has long used multiple identities to operate in different countries. In his early years, he mingled in online gambling circles, then shifted to capital operations, controlling Hong Kong-listed companies through shell acquisitions, and once used hundreds of millions of Hong Kong dollars to buy into Evergrande Property's unlisted shares. He also invested in biotech companies and established charitable funds to create a social image of a "successful businessman."
