第二次直奉戰爭
The prelude of the Second Zhili–Fengtian War was the First Jiangsu-Zhejiang War, which broke on 3 September 1924, and provided a direct excuse for the Fengtian clique to start the war. The next day, Zhang Zuolin held a conference at his residence. Every Fengtian army officer ranking brigade commander or higher was in attendance. Here, Zhang decided to formally declare war on the Zhili clique, and on September 13 all trains running on the Beijing–Fengtian Railway stopped.
