Then go to the local education bureau to sign up for the teacher qualification examination. At the time of application, primary school, junior high school (junior college degree) and senior high school (undergraduate degree required) should choose one of the three.
Then you need to prepare for the lecture exam.
The exam is: writing a lecture in the morning (3 hours) and conducting an interview in the afternoon. (Music textbooks and teachers' books are allowed to be specified)
If you pass the interview, the provincial and municipal education departments will issue the teacher qualification certificate within three months.
