You don't need to go to the public security bureau for filing, but it depends on what kind of training institution it is. If it is a private compulsory education or extracurricular tutoring and training institution, it should go to the Education Bureau to apply for a school license, but now 90% of the country has not accepted it and can't even open it. If it is a vocational skills training institution, it is necessary to go to the Human Resources Management Bureau for the record of private vocational training institutions. At present, only vocational skills training institutions can apply for school qualifications.
