Mao Zedong's grasp of the war situation was always just right. In order to reduce casualties, he suddenly withdrew from the battle after Zhou Hunyuan felt the Red Army's powerful strike, so that his opponent did not know what medicine he was selling in the gourd, so he shrank in the castle and did not dare to attack rashly. This is exactly the effect he wants. Although the fight against Lu Banchang failed to achieve the expected victory or even ended in a "defeat", it greatly dampened Zhou Hunyuan's spirit and made Chiang Kai Shek's plan of "one man in charge of the pass" wishful thinking. Lu Banchang thus won extremely precious time and space for the Red Army to successfully cross the west, jump out of the enemy's heavy encirclement, and realize the overall strategic goal of crossing Chishui four times.
