When it comes to Chiang Kai-shek's house arrest of Zhang Xueliang, we have to mention the Xi incident. On the eve of the Xi Incident, Zhang Xueliang also responded to the call of the broad masses of the people to stop the civil war and unite against Japan, and then conspired with another patriotic general, Yang Hucheng, to arrest Chiang Kai-shek in Xi 'an and force him to resist Japan. Today, the vast number of history books praise Zhang Xueliang's feat in a positive tone. But if we look at this issue from the standpoint of Chiang Kai-shek and the Kuomintang, we can see how serious Zhang Xueliang's crime is. Chiang Kai-shek was the supreme ruler of the Kuomintang at that time. As a senior general under Chiang Kai-shek, Zhang Xueliang arrested Chiang Kai-shek, which was tantamount to rebellion and rebellion, and was a great sin that no ruler could tolerate. This kind of crime, if put in the ancient feudal dynasty, should have severely punished Jiuzu. Yang Hucheng, another planner of the Xi incident, was not so lucky. He was quickly arrested by Chiang Kai-shek and secretly executed. And Zhang Xueliang and Jiang only sentenced him to life imprisonment, which is already a light sentence. It is said that as a result, in his later years after regaining his freedom, Zhang Xueliang once said that he was ashamed of Jiang's cultivation and regretted launching the An incident.

Zhang Xueliang's house arrest is a light sentence. Even if someone wants to save him, he will refuse others' help in order to atone!
