Although An Chunshan was impatient, and it was more difficult to say that the act of killing the soldiers on the spot was more appropriate, his bravery and good fighting were indeed well-known in the Sui army, in addition to the first merit in the Battle of Baotou, the Battle of Suixi was also a pioneer, even if he was shot in the thigh, he refused to withdraw, which was quite praised.
When discussing the establishment of the "Heart-Pulling Commando Brigade," Fu Zuoyi called up a meeting of generals above the regimental commander, and An Chunshan was the first to stand up and speak: "Our country is a weak enemy and a strong enemy, so although it is a long-term war of resistance, it must always be done, and there must always be a war, otherwise it is not called the War of Resistance, it is called chaos!" Dry and mixed is not the same, playing or not fighting is not the same, if it is mixed, I will now pick a pick, take a long vacation, go back to my hometown. If I want to do it, then I am willing to be the first to go to the soup and charge the battle. ”

On the battlefield, the momentum is the head, and Fu Zuoyi's commando commander really chose the right person. In the First Battle of Baotou, because the An Chunshan Regiment was an ordinary infantry regiment and only adapted to general field battles, it suffered a lot of losses. This time, Fu Zuoyi set up the "Heart-Pulling Assault Brigade" with the An Chunshan Regiment as the backbone, and then drew elite troops and strong generals from other units such as the Suiyuan Guerrilla Army and the Wulin Garrison Brigade, and then gathered everyone together for special training.
The first is to simulate the environment in Wuyuan City, so that the commandos can practice night battles and street battles, as well as how to fight more with less, how to explode, and how to defend themselves. What the average soldier masters, they must master, and what the ordinary soldiers do not master, they must also master. Secondly, referring to the lessons learned from the Battle of Baotou, links such as assault setbacks were added to the exercise to improve the response capacity of the commandos.
The special training was related to the success or failure of the "heart-digging tactics" and even the Wuyuan Campaign, so Fu Zuoyi attached great importance to it, and often came to the commando team with his staff personnel to personally give in-depth and detailed explanations and points from the various situations assumed in the exercise to some methods of handling setbacks.
During the training period, the commando team practiced strict confidentiality, and only allowed to enter and exit the area where they were located. Even if you have to go out, you must wear a piece of civilian clothing in order to avoid the reconnaissance of Japanese aircraft. At the same time, all training and exercise activities are carried out using morning fog or dark night.
Fu Zuoyi mobilized the whole family on this side, while Kuwahara on the other side was still on his second leg. The failure of Fu Zuoyi's "set of horse poles" made him very proud: it turned out that Fu Mou's repeated moves were only a few moves, which would lure me out of the city, if I couldn't kill them, what else could he do?
Wuyuan consisted of the old city of New Town, with Kuwahara himself leading the Suixi Garrison to defend the new city, King De's puppet Mongolian division guarding the old city, and Wang Ying's "Suixi Autonomous United Army" stationed on the outskirts of Wuyuan. After completing the deployment, Kuwabara turned around with his hands behind his back, quite self-satisfied.
Standing on three feet, I am still afraid of who will come, I do not rely on any reinforcements, I can also defend the Five Plains, and Fu Zuoyi, you stay in the countryside, don't dream of returning to the city.
On the night of March 20, 1940, the chief of the secret service who was having a good dream was suddenly awakened by the sound of gunfire, and someone reported to him: Fu Zuoyi has entered the city!
