Mao Renfeng, a native of Quzhou, Zhejiang Province, graduated from Huangpu Ivy, followed Chiang Kai-shek all his life, was a hardcore confidant of Chiang Kai-shek, was the core figure of the Investigation and Statistics Bureau of the Military Commission of the National Government, and succeeded dai Kasa as the director of the bureau after his death, and was once called the "four secret agents" together with Dai Kasa, Li Shiqun and Xu En, and was later promoted to the second rank general of the National Revolutionary Army.
Shen Drunk said: "Mao Renfeng gives people the impression of being very loyal and old-fashioned, and he is a famous smiling tiger with a smile when he smiles. For example, before the defeat of Taiwan, Mao Renfeng created the Zha Di Dong massacre that shocked the whole country, including Jiang Zhujun, who was only 29 years old.
After arriving in Taiwan, because of his separation from Chiang Ching-kuo, Mao Renfeng was once very unsafe in Taiwan, and Lee Teng-hui took the opportunity to attack, and one day, Mao Renfeng was suddenly shot and killed, and twelve of his seventeen men died, and he survived.
The feud with Chiang Ching-kuo is entirely due to power, because of the power of the intelligence system. Chiang Kai-shek instructed Chiang Ching-kuo to gradually integrate Taiwan's intelligence agencies so that the pace was unified and the information accurate. Moreover, Mao Renfeng, who prides himself on Chiang Kai-shek's trust in Chiang Kai-shek, went so far as to confront Chiang Ching-kuo's leadership of the intelligence agencies at the meeting of the Central Standing Committee, saying that intelligence work is a very professional thing and that laymen cannot lead insiders. Since then, he has formed a bond with Chiang Ching-kuo.
Of course, Chiang Kai-shek trusted his son even more, and Mao Renfeng's humiliation was nothing more than his own credit, however, when the soldiers were defeated in Taiwan, many things were being reshuffled, and the merits of that year had long been unvalued, so in the fight with Chiang Ching-kuo, Mao Renfeng's defeat was almost doomed.
After a period of open and secret struggle, Mao Renfeng finally realized that he could not fight the crown prince Jiang Chingguo, and Chiang Chingguo had already sharpened his sword and was not only going to overthrow Mao Renfeng, but also to further collapse the secret bureau controlled by Mao Renfeng.
Therefore, Mao Renfeng finally gave in, and he asked Song Meiling to come forward to coordinate the relationship between him and Chiang Ching-kuo, and Song Meiling did not want Chiang Ching-kuo's forces to be too powerful and the whole person was too poisonous, so he was willing to mediate for Mao Renfeng in front of Chiang Ching-kuo, and finally made Chiang Ching-kuo give up his plan to further liquidate Mao Renfeng.
As Taiwan's intelligence power gradually entered Chiang Ching-kuo's palm, his conflict with Mao Renfeng slowly dissolved. However, after so many years of open and secret struggle, coupled with overwork, Mao Renfeng finally fell ill and went to the hospital for a check, liver cancer. In October 1956, Mao Renfeng died of illness at the age of 58.
