They mainly selected athletes with good explosive force, fast speed, physical fitness and joints, such as shot put, sprint, long jump and high jump students. After the selection, I will talk to the parents of the students, which is the most difficult link. "We all go to work at home, but parents worry a lot. They are afraid that their children will not be able to practice weightlifting for a long time. They are afraid that their children will suffer hardships.

Unless they did not get any results, the average parent could stay and concentrate on the practice until they reached the provincial team, the national team or entered the university. "
