In 1945, Chinese American Milani fled to the Embassy of the Republic of China in the UK, and she brought intelligence about the Yalta secret agreement. Military attaché Liang Tong wisely forced the Yalta agreement to be made public, shocking the world. In order to strengthen his control over the regime, Chiang Kai-shek did not hesitate to negotiate peace with the Japanese. The Communist Party firmly opposed dictatorship for the long-term interests of the nation. As a member of the Communist Party, Liang Tong discovered the conspiracy and passed it to his superiors. Liang Tong reported the Kuomintang's takeover plan to his superiors, providing necessary reference for the CCP to march into the Northeast. The Kuomintang betrayed the "Double Ten Agreement" and the civil war broke out. Our East China and Central Plains Field Army grabbed Huang Baitao's Corps, which was fleeing south, and Liang Tong, in accordance with the command of the Communist Party, used the high position of the Kuomintang to deploy, making the battlefield situation of the Kuomintang army more chaotic. The Kuomintang troops were divided and eliminated one by one. Liang Tong eventually led his troops to revolt in Sichuan, thus breaking the Kuomintang's delusion of "defending Sichuan and waiting for the situation."
