On August 23, some Japanese troops stationed in Shijiazhuang reinforced westward. At that time, it rained for days in North China and the river flooded, which brought inconvenience to the Eighth Route Army's attack. The troops of the Shanxi-Chahar-Hebei Military Region dispatched troops to continue to attack the railways, bridges and tunnels occupied by the Japanese army in an all-round way. Under the brutal "mopping-up" of the Japanese invaders who killed everyone and burned every room, Nie Rongzhen led the soldiers and civilians in Shanxi, Chaji and Hebei to resolutely oppose the "mopping-up". Everyone shouted a slogan: "When the enemy enters the village, we will leave the village, and when the enemy leaves the village, we will enter the village; If the enemy doesn't come, blow up bridges, destroy tunnels, burn sleepers and cut wires; When the enemy came, they lured them with scarecrows, bombed them with grenades, bombarded them with stone mines, and fought back bravely against the invaders with the wisdom of the people of China. "
