Narrator: Ge Linnan

At the beginning of April, after crossing the Wujiang River in the south, the Central Red Army went straight to Guiyang and once hit the airport 20 kilometers away from Guiyang City. Chiang Kai shek, who was overseeing the battle in Guiyang, had only one regiment. When he saw the Red Army approaching Guiyang, he urgently ordered the main force of the Yunnan Army to reinforce urgently, and strictly ordered the Hunan, Guangxi and other armies to stop the Red Army. The alarm was not lifted until it was discovered that the Red Army was advancing rapidly from the east to the southwest in Guiyang.

While the Kuomintang troops were concentrating to the east of Guiyang, the main force of the Central Red Army suddenly turned southward from the Qingshui River area, and marched at a speed of 60 kilometers a day toward Yunnan, approaching Kunming.

On April 29, the Central Committee of the Communist Party of China and the Central Revolutionary Military Commission issued an instruction to cross the Jinsha River quickly and establish a Soviet area in western Sichuan.
