In PE classes, the content of PE classes is too simple and there is no systematic guidance system for PE, so there are no PE teachers, so you should read a little. I also learned about the earth spring. After a short while, students lose interest in learning due to the lack of systematic professional education. Teaching was ineffective, and such teachings became meaningless, and most students not only enjoyed the fun of tai chi, but also regarded tai chi as a boring course with no energy or knowledge. It was. Teaching must have good educational content, and only good educational content can teach good students.
