The Battle of Sidu Chishui was a decisive mobile warfare campaign by the Central Red Army on the way to the Long March after Zunyi Conference, under the dangerous conditions of siege and blockade by hundreds of thousands of Kuomintang troops. Under the command of Chairman Mao Zedong, Vice Chairman Zhou Enlai and Commander-in-Chief Zhu De, the Central Red Army adopted a highly mobile policy of mobile warfare, galloped across the vast areas of Sichuan-Guizhou-Yunnan border, actively searched for fighters, effectively mobilized and annihilated the enemy, and completely shattered the arrogant plans of Chiang Kai-shek and other reactionaries to encircle the Sichuan-Guizhou-Yunnan border, and the Red Army achieved a decisive victory in strategic shift.

Mao Zedong commanded the Central Red Army to cross the Three Rivers six times in three months and move to Sichuan, Guizhou and Yunnan provinces. He skillfully interspersed in the encirclement and suppression of the Kuomintang army's heavy group, constantly made fighter planes, annihilated a large number of enemies in the movement, firmly grasped the initiative of the battlefield, and achieved a brilliant example of the Red Army's long March history in which the few prevailed and the passive took the initiative.
