The original text of some friends’ questions:

I don’t understand two points. One is how Zhao Dongping can join the fifth-class unit with this condition, and the other is how can the squad leader become the instructor of Zhao Dongping at his age. He should be a soldier who performs special tasks, at most a squad leader.

Yao Shao’s answer:

Many friends have asked this question, so let's answer it here first. Zhao Dongping is not a soldier's child, but simply said that he is not a child of a high-ranking official. The five-category special forces are special forces with normal training losses on the training ground and will perform special and no international missions when necessary. Without a strong political background and considerable loyalty, he cannot be admitted. It is impossible for him to join the five-category forces in his childhood. The only way is to two thousand and two thousand years later, the five-category forces will be in the next five-category forces.

In order to improve the combat experience of the troops, a group of soldiers who have proved absolute loyalty to the Party and the people and have rich practical experience were absorbed. Most of these soldiers came from the garrison troops on the border of Afghanistan, they fought against the East Turkish guerrillas, and the Indian-Tibet border special forces on the border of Afghanistan. Such over-age trainees could no longer receive systematic training. The school would assign them to the best soldiers who have been promoted to squad leaders, and the squad leaders were the instructors who were all wrong.

Is this explained clearly?
