西南六省军阀在南京国民政府建立后纷纷投靠蒋介石，但始终与蒋介石中央政府貌合神离，以求保持半独立状态。蒋介石对这些拥有实力而又非自己嫡系的军阀既要笼络收买，又想排斥消灭。当中央红军从闽、赣出发，向西部转移时，蒋介石企图趁消灭红军之机，削弱和控制地方势力，以收到一石二鸟之功效。西南军阀既怕红军入境，动摇自己的地位，又怕蒋介石乘机染指他们的地盘。红军巧妙利用这一矛盾冲突，打破了蒋介石的围追堵截，从而取得了长征的伟大胜利 After the establishment of the Nanjing National Government, the warlords in the six southwestern provinces came to visit Chiang Kai-shek one after another, but always kept a close contact with the Central Government of Chiang Kai-shek in the hope of maintaining a semi-independent status. Chiang Kai-shek wants to win over these warlords not only because of their strength but also of their own. When the Central Red Army proceeded from Min and Gan, and shifted to the west, Chiang Kai-shek attempted to weaken and control the local forces by taking the opportunity to destroy the Red Army and receive the effectiveness of two birds and one stone. The southwest warlords are afraid of entering the country by the Red Army and shaking their own positions. They are afraid that Chiang Kai-shek will take advantage of the opportunity to invade their sites. The clever use of this contradiction by the Red Army broke the siege of Chiang Kai-shek and thus achieved the great victory of the Long March
