The Chinese Red Army jumped out of the encirclement of Kuomintang by unexpectedly crossing the Chishui River four times, and eventually survived the anti-communist military campaign of Chiang Kai-shek.

Zhu De, Chen Geng and Song Renqiong successfully covered the flank of Mao's main force and stopped the Sichuan KMT army at Tucheng.

On January 29, the Red Army crossed over the Chishui River near Tucheng and continued marching west to enter Weixin County in northeastern Yunnan.

Peng Dehuai and Yang Shangkun led the 3rd Legion of Red Army marched south and occupied the Loushan Pass after the local KMT troops were mostly sent westward to the other side of the Chishui River.

When Chiang realized the real move of Mao, the vanguard of Red Army led by Xiao Hua had already crossed the Wu River and approached the defenseless Guiyang.

In order to defend the airport so that he could evacuate the KMT leadership group, Chiang dispatched Sun Du's troop, based in Dading, to reinforce Guiyang, leaving a wide-open path for Red Army to enter the northern Yunnan.

After the Zunyi Conference, Mao Zedong replaced Bo Gu and Otto Braun as the chief commander of the army, and then started the Battle of Chishui River.
