Anyone who knows Chiang Kai-shek knows that he is a suspicious person, just like Zhu Yuanzhang at that time, and he does not trust anyone so much. Moreover, in Chiang Kai-shek's cognition, it has always been believed that the generals who graduated from the Whampoa Military Academy are more loyal than the generals from other places. In addition, Chiang Kai-shek also believed that people born in his ancestral hometown of Zhejiang were relatively loyal, so when dealing with these generals, Chiang Kai-shek would treat them differently. For those who graduated from the Whampoa Military Academy or were from Zhejiang Province, it would be better and more reusable. For those local military origins, they were relatively poor, and even once called these people miscellaneous generals.

In fact, these generals, who are called miscellaneous armies, are not as bad as the name calls them, and their combat command ability is also worthy of recognition. Unfortunately, they all lost in a certain campaign and were eventually forced to be absorbed by Chiang Kai-shek and become troops under the Nationalist government.
After becoming miscellaneous generals, these people's lives were also very difficult, because they could not be reused by Chiang Kai-shek. Even in the same matter, if a mistake is made, those who are protected by someone at the top of the Kuomintang will be given a lenient punishment, or they will do a little superficial work out of human feelings, or even directly stop it. And if there is no one above, like this kind of general who is not reused, they will be punished very badly, and they may even be removed from their posts and imprisoned.
It can be seen from this that the status of miscellaneous generals is very low in Chiang Kai-shek's troops, and it can be said that they are at the bottom of the Kuomintang generals. In stark contrast, the well-known graduates of the Whampoa Military Academy, a group of generals who held a very high status in Chiang Kai-shek's army. Not only can you get good treatment, but you will also have more opportunities to show yourself than others.
If you want to break down, Chiang Kai-shek's internal generals in the Nationalist army can be divided into three levels. The first is the most inferior miscellaneous general, this kind of person is the most unpopular category in the whole team, and its main representative figures are Zhang Zizhong, Feng Zhi'an, and so on. The second is the relatively high-status Huangpu generals, who have been following Chiang Kai-shek in the southern expedition to the north, and have been appreciated and valued by Chiang Kai-shek, such as Du Yuming and Hu Lian.
The last category is the highest-ranking category in the Kuomintang army, they not only have the status of graduates of the Whampoa Military Academy, but also belong to Zhejiang people like Chiang Kai-shek, so they can definitely be regarded as reds in front of Chiang Kai-shek. People with such dual identities are relatively few in Chiang Kai-shek's ranks, so they are also the people chiang kai-shek trusts the most and is the most important. The representative figures of this type of general are Hu Zongnan and Chen Cheng, among whom Hu Zongnan is known as "the first protégé of the Son of Heaven", while Chen Cheng is known as the "small chairman" and is very much relied on by Chiang Kai-shek.
In fact, when we look back at history now, we will find that Chiang Kai-shek's way of appointing talented people is too arbitrary and one-sided. Relying solely on ancestral origin, graduation school, and other external factors to judge whether a person is loyal is really unflattering.
Chiang Kai-shek's choice of his own confidants in this way is not difficult to understand. In Chiang Kai-shek's heart, it has always been the home country rather than the country, and the home is in front and the country is in the back. Nepotism is to maintain their own dictatorship, how can such a person win the hearts and minds of the people? Failure is already predestined.
