Before and after the Xi'an Incident in December 1936, He Zhuguo followed Zhang Xueliang closely and supported the Chinese Communist Party's idea of a peaceful settlement of the Xi'an Incident. After Zhang Xueliang sent Chiang Kai-shek to Nanjing and was detained, in January 1937, a senior general of the Northeast Army produced a main and a faction and a main battle group on how to rescue Zhang Xueliang. He Zhuguo and Wang Yizhe were the representatives of the Harmony School. The Harmony School believed that the Xi'an problem should be solved first and then Zhang Xueliang was rescued. On February 2, the young main officer of the Northeastern Army killed Wang Yizhe, and He Zhuguo fled into Yanghucheng Mansion because of news. Since then, in order to stabilize the Northeast Army, He Zhuguo met with CCP leader Zhou Enlai and others many times, and soon stabilized the Northeast Army. Soon, He Zhuguo went to Nanjing on behalf of the Northeast Army, and went to Xikou to meet with Zhang Xueliang to agree on the reorganization of the Northeast Army. Chiang Kai-shek then appointed He Zhuguo as the deputy director of Xi'an Xingying, and then appointed him as deputy director of the Yu Ansu Soviet Military Reorganization Committee to reorganize the Northeast Army who had just entered the Henan Anhui Soviet. After the reorganization was completed, He Zhuguo served as the commander of the 2nd Army of the Central Cavalry and remained in the northwest.
