He Zhuguo
In January 1935, Chiang Kai-shek changed the headquarters of the bandits from Henan, Hubei and Anhui to Wuchang, the chairman of the military committee of the National Government, and Zhang Xueliang served as the director of the camp. Chiang Kai-shek was preparing to transfer the Northeast Army to Guizhou, but He Zhuguo suggested that Zhang Xueliang transfer the Northeast Army west of Luoyang to stabilize the military and prepare for the recovery of the Northeast. He Zhuguo's proposal was adopted by Zhang Xueliang, who agreed with Chiang Kai-shek. Soon, Zhang Xueliang formed the cavalry corps with the seven cavalry divisions of the Northeast Army and the central cavalry dispatched by Chiang Kai-shek, and appointed He Zhuguo as commander.
