Jiang Weiguo nominally became the second son of Chiang Kai-shek. Jiang Weiguo is not Chiang Kai-shek's own son, but Chiang Kai-shek regards him as a parent-child, so he is in the genealogy. After Jiang Weiguo arrived in Xikou, he was raised and cared for by the Chiang family like Jiang Jingguo. He called Mrs. Wang his grandmother. Chiang Kai-shek treated Jiang Weiguo as his own, and Jiang Weiguo had deep feelings for his "father". As long as Jiang Weiguo said he missed his father, Chiang Kai-shek would pull him to his side. People often see Chiang Kai-shek holding Guo Wei in his arms and sometimes letting him ride on his shoulders, which is very close. Like Jiang Jingguo, Chiang Kai-shek was very strict about Jiang Weiguo's education. A few years later, the boy became a famous second-class general of the national army and the secretary-general of the National Security Committee of Taiwan Province provincial authorities.

At the beginning of 1989, a newspaper published a report about his life for the first time publicly. His surname is still a mystery, saying that "whether he is the son of Chiang Kai-shek or the son of Dai has not been proved to be a mystery" and "I hope to find more information to find out" and so on. "Dai's son was adopted by Chiang Kai-shek." This is what Mr. Mao Bingyue, deputy director of Fenghua County Committee of the Chinese Revolutionary Committee, personally heard from Sister Chen Zhijian who taught Jiang Weiguo's foster mother Yao Yecheng to study culture. She also said that it was only because Chiang Kai-shek regarded Guo Wei as his own, his family kept it a secret, and it was not convenient for others to disclose it, so it is still unknown.
