Surrounded by the Japanese army in a deep ditch, the director department of the empty city, the main force of the Eighth Route Army, successfully broke through.

Doucun Village, Wutai County, Shanxi Province is located in the southwest of Taihuai Town. It is the western outpost guarding the leading organs of the Shanxi-Chahar-Hebei border region, close to Wutai County occupied by the Japanese army. 1939 Spring, 120 Division 359 Brigade 7 17 Regiment moved to Doucun for rest. However, the Japanese will not let the Eighth Route Army rest in peace and then come back to grow bigger. That was not the case. Just in May, more than 5,000 people from the 109 Division and the Independent 3 Brigade were dispatched to attack the Eighth Route Army in Taihuai area in four ways, in an attempt to attack the 359th Brigade of the Eighth Route Army in Taihuai area.

On May 9, a large Japanese army set out from Wutai County to "mop up" the Taihuai area and secretly approached Doucun. After receiving the investigation report, the head of the regiment and political commissar Yan quickly assembled troops and set off at dawn on 10, moving closer to Longquanguan area, Fuping County, Hebei Province, where the Jinchaji Military Region is located. Fortunately, God never shuts one door but he opens another. After asking, I learned that there is a path leading to the temple castle in Fan Shi, which can avoid the enemy. Liu Zhuanlian immediately decided to change the transportation trench company in the supply office to avant-garde, and quickly moved to Shentangbao in the brigade headquarters along the narrow path pointed by the villagers.

Contact with the brigade was cut off because the radio station was broken. They don't know that at this time, a Japanese army, after capturing the Shentangbao where the brigade headquarters is located, is heading for Tongqiangou where the 7 17 regiment is located along the road pointed out by the villagers. At dusk, the trench company met this devil. The enemy's superiority is based on the superiority of numbers and weapons. First the mountain artillery bombarded fiercely, and then the cavalry attacked. The trench had no choice but to retreat to the copper coin ditch.

Facing the crisis, Liu Zhuanlian forced himself to calm down. Although there were explosions around him and the air churned over the map from time to time, he smoothed the map without scruple and continued to observe it carefully. Suddenly, he found that there was a gap of about 3 kilometers between Taihuai Town and Dongtai in Wutai Mountain. I see. Leave this area, kill a carbine and return to Taihuai before the enemy camp. After a brief exchange of views with Yan, he immediately convened a meeting to plan the deployment, and then implemented a breakthrough under the cover of night arrival. In order to ensure the safety of the whole group, after everyone dispersed, Liu Zhuanlian asked the courier to call Tan Lianlu, the company commander of Company 7, and asked him to take 1 in the back to contain the enemy, try to confuse the enemy, sing empty words to the enemy, and other large troops cut in and then retreat.

At night, under the leadership of an old woodcutter, the whole group held their breath, helped each other, walked carefully step by step along the narrow path led by fellow villagers, and climbed to the top of the mountain with difficulty. Night, quiet. In addition to the rustle of clues, there were sparse gunshots at the foot of the mountain. It was the company commander of Company 7 who led a small team to deal with the enemy. After a hard night's March, at dawn, the 7 17 regiment climbed to the top of Wutai Mountain and finally jumped out of the enemy's encirclement.
