At present, there is no formal certificate in China, especially boxing. There are boxing certificates and coaching certificates abroad. As far as I know, there seems to be only one boxing referee certificate in China. If you want to be a coach, you can only go to an interview to show your strength and lecture level. In addition, many places will judge your coaching level by your previous record as an athlete. Although it is not very scientific, it is caused by our national conditions and there is no way.
