He Yingqin
With the start of the Second Sino-Japanese War after the Marco Polo Bridge Incident in 1937, He Yingqin was appointed as chief of staff and worked with Chiang for drafting military plans. In 1944, when his title of Minister of War was taken over by Chiang's favorite, Chen Cheng, He was appointed as General Commander of the Chinese Military Area, which was an honorable title instead of real power, and was sent to Yunnan to train the Chinese Expeditionary Army, which was set up under the proposal of Joseph Stilwell, for assisting in Allied operations in Southeast Asia.
