During the Republic of China, there were two well-known figures among the Gui warlords, namely Li Zongren and Bai Chongxi. The two were originally classmates, and in that chaotic world, the two cooperated and gradually unified the whole territory of Guangxi and sat on Guangxi. Bai Chongxi was also known as "Little Zhuge Ge" because of his resourcefulness in repeated battles.
However, the resourceful "Little Zhuge Ge" was defeated in the War of Liberation and eventually fled to Taiwan with Chiang Kai-shek. Because the Warlords of the Gui clan, headed by Li Zongren and Bai Chongxi, have been wrestling with Chiang Kai-shek for many years, Bai Chongxi was not trusted by Chiang Kai-shek after he arrived in Taiwan, but only held a series of false posts such as "strategic adviser to the presidential palace" and was also monitored by Chiang Kai-shek at all times, so Bai Chongxi's life in Taiwan was not good.

In 1966, Bai Chongxi died suddenly at the age of 73. Because Bai Chongxi died suddenly and violently, and it is said that the body turned green during the autopsy, there are various theories about the cause of Bai Chongxi's death.
Regarding the cause of Bai Chongxi's death, the most widely circulated theory is that he was poisoned by Chiang Kai-shek. Because Bai Chongxi's body turned green when he died, many people believe that Bai Chongxi died of poisoning, which was also confirmed by the Kuomintang agent Gu Zhengwen, but this statement was eventually denied by Bai Chongxi's son Bai Xianyong.
Bai Xianyong's denial is also justified, first of all, he believes that Bai Chongxi has no real power after arriving in Taiwan and will not pose a threat to Chiang Kai-shek, and Bai Chongxi is also a well-known figure, and if Chiang Kai-shek wants to assassinate him, it will definitely cause a major dispute. Chiang Kai-shek could not have taken such a big risk to assassinate a man who would not pose a threat to himself.
In addition, Bai Xianyong also said that Gu Zhengwen was just a small agent in Taiwan, and he was simply a nameless person. Chiang Kai-shek would not have sent such a nameless person to assassinate Bai Chongxi. Bai Xianyong believes that Gu Zhengwen's statement is only for fame, for the sake of eyeballs, in order to attract people's controversy.
In recent years, there has been another theory about the cause of Bai Chongxi's death, saying that Bai Chongxi died because of "immediate wind", which is speculated based on the Chinese medicine prescription that Bai Chongxi took before his death. Because Bai Chongxi took a lot of aphrodisiac drugs before his death, and Bai Chongxi's attending doctor Lai Shaoling also admitted to adding aphrodisiac drugs to Bai Chongxi's prescription, so Bai Chongxi's death was widely known.
According to Lai Shaoling, these several aphrodisiac drugs were asked by Bai Chongxi to add, because Bai Chongxi has been living alone since his wife's death, and usually there is no one to talk to, and the female nurse who takes care of her is an optimistic and cheerful person, and soon Bai Chongxi is attracted to her, and the two have feelings of affection, so he needs these aphrodisiac drugs.
However, this statement was also rejected by Bai Chongxi's son Bai Xianyong. According to Bai Xianyong, their family has always had inherited heart disease, including Bai Chongxi himself who also suffered from heart disease for genetic reasons. Bai Xianyong revealed that bai Chongxi died late at night, when his aide-de-camp was at his side, and the adjutant first discovered Bai Chongxi's death. There is no one else around Bai Chongxi, so it is possible to overturn the claim that Bai Chongxi died of "immediate wind".
Because Bai Chongxi had a familial heart disease, and his health was not good at that time, So in the end Bai Chongxi died of acute myocardial infarction. When myocardial infarction occurs, it is sudden and violent, and because Bai Chongxi is suddenly violent, there are many rumors circulating in the anecdotes, and the cause of Bai Chongxi's death is confusing.
Bai Xianyong revealed that the cause of his father's death was actually very simple, that is, heart disease caused by myocardial infarction.
