The second reason is that Liu Zhi is easier to get support than other candidates. At that time, Chiang Kai-shek chose Commander-in-Chief. In fact, there were two candidates, one was Herry Liu and the other was Jiang. But unfortunately, Jiang himself failed to live up to expectations, and often lingered in romantic places, ignoring official business, so he had to choose Herry Liu. The third reason is that Chiang Kai-shek didn't trust him, Qin Ying. Herry Liu didn't take office long. As far as his ability is concerned, He Qinying, who was Chiang Kai-shek's clique at that time, actually questioned that he could not be commander-in-chief.
So he once again suggested to Chiang Kai-shek that Bai Chongxi should be the candidate for unified command. But at this time, Chiang Kai-shek listened to Chen Cheng and began to suspect that he had been bought by Bai Chongxi. So Chiang Kai-shek rejected He's request and maintained his original decision. The fourth reason, I have to. At that time, another person also questioned Herry Liu's ability and concluded that he could not keep Xuzhou. This man was the chief of staff at that time, so he suggested that Chiang Kai-shek temporarily let Bai Chongxi command the battle and then return the commander-in-chief to Herry Liu.
Chiang Kai-shek also realized the problem, changed his mind and wanted to directly put Bai Chongxi under unified command. At that time, Bai Chongxi also agreed to this matter, and offered to mobilize his own troops to take part in the battle of Xu Mu. Unexpectedly, the next day he suddenly changed his mind and refused to unify the command of Xuzhou and Central China. But at that time, the Huaihai Campaign was ready to go. Even if we knew that Herry Liu could not command the battle, we should bully the weak and fear the hard.
