First of all, it depends on the organizational nature of your school, whether it is a company, a partnership or a private non-enterprise If it is a private non-enterprise and some of them have no legal person qualification at all, then there is no question of the legal representative serving as the principal.

According to the Law of People's Republic of China (PRC) on the Promotion of Private Education, the legal representative of a private school is the chairman, director or principal.

You don't have to be a principal and a legal representative.

Regarding the qualification requirements:

The school board or council is composed of the sponsor or his representative, the principal, representatives of the staff and workers and other personnel. More than one third of the directors or directors should have more than five years of education and teaching experience.

The school board of directors or council consists of more than five people, with a chairman or chairman. The chairman, directors or the list of chairmen and directors shall be submitted to the examination and approval authority for the record.

Finally, many training schools are just scratching the edge and have no qualifications at all, so none of these requirements mentioned above can be discussed.
