In the final analysis, the reason is that the internal composition of the Kuomintang is too complicated and there are many factions. Reflected in the deep contradictions between central factions, between central and local governments. All kinds of problems before the collapse of the national government originated from this reason. This situation existed seriously at the beginning of the founding of the Kuomintang. From the beginning of warlords in Guangdong and Guangxi, to Wang Jiang * * *, to the last Chiang Kai-shek, and then to the victory of the Anti-Japanese War, the National Government was always in a state of division. To tell the truth, this situation cannot be fundamentally changed by any manpower, which leads to the weak dominance of the government. In order to maximize centralization, Chiang Kai-shek also indulged in corruption. Losing people's hearts is inevitable. Even though the number of equipment and troops is ahead, due to the lack of cooperation between the troops, they are always defeated by their opponents, which eventually leads to defeat. Of course, the lack of military strategic spirit and political education and the lack of excellent generals are also very important.
