Actually, there was no arts performance planned at the border defense entrance. In order to cooperate with the armed police and the Yun Province military district, the art troupe adjusted their performance plan at the last minute and went to the entrance where Qin Maosheng's subordinates would appear.
To ensure the safety of the soldiers from the troupe, all the soldiers knew that they were just cooperating with a decapitation strike. They mustn't leave the camp alone. After the performance ended, everyone would stay in the camp. No one was allowed to go out.
There were very few female soldiers at the border defense and the border gates. There weren't many female soldiers in the company. Almost all the communication was done by male soldiers. When the arts troupe came to the company for the arts performance, they went to the village to perform. Hence, Qin Maosheng, who knew that the arts troupe had come to the border defense, treated the female soldiers as his targets.
