In November 1949, the Second Field Army advanced into the southwest, and the battle to liberate Chongqing began. Chongqing used to be the capital of the people, both geographically and politically, it was very important, so Chiang Kai-shek deployed heavy troops in an attempt to use Chongqing as the last base and resisted stubbornly. In Chiang Kai-shek's heart, even if this battle cannot be won, it can drag on for at least a year and a half to create time for **, however, the reality slapped him in the face, and in less than a month, Chongqing was liberated!What is the reason for this?Chiang Kai-shek definitely never imagined that he would be planted in the hands of this person - Liu Zongkuan, then the chief of staff of the Lieutenant General of the Southwest Governor's Office. 
It turned out that when the Kuomintang held a meeting in August 1949 to deploy defense, Liu Zongkuan said through Hu Zongnan's deputy staff officer Shen Ce that according to the experience of Deng Aihuashu during the Three Kingdoms period, the PLA would definitely march along northern Sichuan, because this road was easier to take. This set of rhetoric not only frightened Shen Ce and Hu Zongnan into a daze, but even Chiang Kai-shek could not distinguish the truth from the false, and finally listened to his words and deployed heavy troops in northern Sichuan. In fact, this was a plan devised by Liu Zongkuan and our army to "divert the tiger from the mountain", attacking from northern Sichuan on the surface, but actually sending a large army to march from eastern Sichuan. Of course, the drama still has to be done in place, when Chiang Kai-shek put all the heavy troops in the northern Sichuan area, Liu Zongkuan took the initiative to ask for orders and led the army to be stationed in the eastern Sichuan area to prevent the PLA from launching a surprise attack. However, in the eastern Sichuan defense line arranged by Liu Zongkuan, the opening for the PLA to advance to the southwest had already been reserved, so when Lao Jiang was still waiting for the PLA in northern Sichuan, our army had already quietly touched the back of his buttocks. If the battle is like this, is there any reason not to lose?
So, why does Liu Zongkuan, as a person on the top side, cooperate with our army?You must know that Liu Zongkuan was born in the Whampoa Military Academy, and he also studied at the Army University, and he was Chiang Kai-shek's protégéIt turns out that although Liu Zongkuan is a student of Whampoa, he still has an identity, that is, Yang Hucheng's nephew, and everyone knows the grievances between Yang Hucheng and Chiang Kai-shek, right?Whose side do you think Liu Zongkuan will be on?At first, Chiang Kai-shek didn't know his identity and wanted to win him over several times, but Liu Zongkuan refused every time with an excuse, until after the Xi'an Incident, Yang Hucheng was placed under house arrest by Chiang Kai-shek, and Liu Zongkuan also completely broke with Lao JiangAs a result, Liu Zongkuan was never reused again, and even asked Hu Zongnan to spy on him secretly, looking for an opportunity to rectify him. 
No, in 1941, Hu Zongnan really grabbed Liu Zongkuan's handle, in fact, it was probably framed, so he was arrested, and Chiang Kai-shek saw it, and he didn't even need to be interrogated, and directly ordered to be shot!You say, with such a relationship, will Liu Zongkuan still be loyal to Lao Jiang?Fortunately, Liu Zongkuan knew a lot of people, and after the intercession of Feng Yuxiang, Yu Youren and others, Liu Zongkuan was released in 1945. It is precisely because of these reasons that Liu Zongkuan, under the lobbying and propaganda of our army, finally agreed to cooperate, which is why we have the story we mentioned at the beginning. It is estimated that if Chiang Kai-shek knew, his mouth would be crooked!I have to say that Liu Zongkuan's contribution this time is very great, if it were not for his plan to divert the tiger from the mountain, our army would not know how many people would have to sacrifice to liberate Chongqing, therefore, the commander of the second field also praised and said: "Liu Zongkuan's role in the liberation of the southwest is better than 100,000 soldiers, which can be called the first merit!"Finally, it is worth mentioning that Liu Zongkuan submitted many applications to join the party in his later years, and it was not until he was dying that the organization officially approved him to join the Communist Party.
