Teachers in primary schools, junior high schools and senior high schools are not prohibited at the national level, but they are absolutely not allowed. Generally, local education bureaus will formulate corresponding policies, but as far as I know, school teachers are basically prohibited from taking part-time jobs in training institutions. In some places, teachers are even prohibited from making up lessons after school, whether in "training institutions" or not.

Part-time teachers refer to short-term teachers employed by some training schools or families. Part-time teachers do not need to perform all the obligations of full-time teachers, nor can they get all the benefits enjoyed by full-time teachers.
