南京国民政府建立之后，四川军阀名义上归顺，但实际上仍拥兵自重，控制川局。蒋介石为了将其势力伸入四川，采取了种种方法：先委任刘湘为川军司令，再派员以参谋团名义入川渗透分权，次又借口追剿红军调中央军入川；继之，又对川军军官实行轮训，最后通过军队整编来削弱川军? After the establishment of the Nanjing National Government, the Sichuan warlords returned their name in nominal terms, but in reality they still held their own weight and controlled the Sichuan Bureau. In order to extend its forces into Sichuan, Chiang Kai-shek adopted various methods. First, Liu Xiang was appointed commander of the Sichuan Army and then sent personnel to infiltrate and decentralize on the name of the staff delegation. He then tried to extort the Red Army from the Central Army into exile on the pretext of expending the Red Army. In turn, Sichuan army officers carry out rotation training, and finally weakened Sichuan army through army reorganization?
