安直戦争
In a repeat of the earlier Zhili–Anhui War, the Fengtian army was to attack the Zhili army on two fronts, east and west. The general headquarters of the Fengtian army was at Junliangcheng, which was also the Fengtian army headquarters of the eastern front. The commander-in-chief of the Fengtian army, Zhang Zuolin, personally led the eastern front and on 29 April 1922, he reached his general headquarters and immediately ordered the attack. Zhang Jinghui was named commander-in-chief of the Fengtian western front, which was divided into three echelons. The headquarters of the Fengtian army's western front was in Changxindian (长辛店), and the Fengtian army in the west was tasked to directly attack the Zhili army's headquarters in Baoding.
