Chiang Wei-kuo
After Sun Yat-sen's death in 1925, Dai changed his name to Chuanxian, "Continuing-Virtue". He jumped into a river and was rescued by a fisherman. After this suicide experience, he converted to Buddhism and was accused by many of being superstitious. His works about Buddhism are published in "The Collection of Mr. Dai Jitao's Discussions on Buddhism" (戴季陶先生佛學論集). He was widely known to be the birth father of Chiang Wei-kuo, the adoptive second son of Chiang Kai-shek. According to popular speculation, Dai believed knowledge of his extramarital affairs with the Japanese woman Shigematsu Kaneko would destroy his marriage and his career, so he entrusted Wei-kuo to Chiang Kai-shek, after the Japanese brought the infant to Shanghai. Yao Yecheng (姚冶誠), Chiang's wife at the time, raised Wei-kuo as her own. The boy called Dai his "Dear Uncle" (親伯). Dai had also fathered a son, Anguo (安國), whom Dai later sent to Germany, to be educated at the Technical University of Berlin. Anguo (Ango) and Chiang Wei-kuo (Wego) were half brothers.
