In conversations with teachers and students, I learned that many senior students are under great pressure to learn, and this pressure comes mainly from their families. In addition to completing the school learning tasks, many students also reported to them Cram school, so many senior students have almost no Sunday. When they are physically and mentally exhausted, they only want to have a comfortable learning state, so they almost never consider maintaining the correct reading and writing posture, so that the number of students suffering from myopia increases year by year.
