The first type is implemented through the relationship between the parent class and the child class.
Compared with the general support of parents in fencing, table tennis, swimming and other events, weightlifting always makes parents have many worries, which also brings a lot of difficulties to the city sports school in selecting materials. Liu Eryong said that weightlifting events rarely took the initiative to send children. After Pingdu, Laixi and other districts and cities held primary school games, the district and city sports schools called them to recommend some young people. The city sports schools sent coaches to go down and have a look. 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. Many children are willing to practice and parents are reluctant to say anything. We just watch the good prospects waste. It's a pity. But when I really came to the sports school and started weightlifting, The average parent also slowly discovered that weightlifting was different from what they imagined and supported their children. Therefore, although we chose five or six of the 10 young people, not many people quit halfway. 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. "
