On the evening of September 16, the battle of Lazikou broke out with the Red Four Regiment to the second battalion as an assault battalion, but after many raids, he failed to attack the pass. The Red Army then changed tactics, with the second battalion and six companies from the front to carry out a strong attack, and two companies used ropes to climb the cliffs on the eastern side of the canyon, and then circled back to the enemy side to command heights.
