But there is a special role in the play: he is a senior official of Zhang Xueliang's northwest suppression general; He is often called "Director Li", but the specific department "Director" is vague, only knowing that he is in charge of telecommunications confidential and intelligence agencies; He is very much in favor of Zhang Xueliang's unwillingness to fight civil war and arrest Chiang Kai-shek, but it is not because of the pain of losing his home like other northeast generals. He is very competent and seems to have won the attention of all parties. Zhang Xueliang was almost obedient to him, and Dai Li, the leader of the military system, also hoped to "cooperate" with him. Chiang Kai-shek specially summoned him to understand the situation a few hours before the "Xi incident" broke out and asked him to go to Nanjing to "help me." After the "Xi Incident", he drafted the "Eight Electrification" that Zhang and Yang made clear. The name of this important person is "Li Qingshan", but in all the historical materials about the "Xi incident", there is no mention of such a person-is it possible that this person was invented by the TV drama creator?
