Eighty-nine years ago today, on December 4, 1936 (October 21, 1936), Chiang Kai-shek went to Xi'an to urge Zhang and Yang to "attack" northern Shaanxi. Chiang Kai-shek held talks with Zhang Xueliang and Yang Hucheng. On December 4, 1936, Chiang Kai-shek completed the deployment of "suppressing the Communist Party" in Luoyang and other places and flew to Xi'an again, using the Huaqing Lake of Lintong as a temporary "suppressing the Communist Party". Chiang Kai-shek summoned the generals of the Northeast Army and the Northwest Army above the division to talk in Lintong, and asked them to obey the order and completely "suppress the Communist Party". Chiang Kai-shek declared: "The suppression of the Communist Party has reached the stage of success in the last five minutes." And threatened to deal with it severely if he opposed the order of "suppressing the Communist Party". Then he presented a showdown to Zhang and Yang, and proposed two plans to force Zhang and Yang to make The first plan is: obey the order to suppress the Communist Party, send all the Northeast Army and the 17th Route Army to the front line of Shaanxi and Gansu, attack the Soviet area in northern Shaanxi, fight against the Red Army, and the Central Army will take over the battle in the back; the second plan is: if you don't want to "exterminate the Communist Party", the Central Army will go to exterminate the Communist Party, transfer the Northeast Army to Fujian, the 17th Route Army to Anhui, give up Shaanxi and Gansu, and the Central Army will "exterminate the Communist Party".
