How to find the principal at home after persuasion

1. Check official website of the school or official website of the Education Bureau to get the contact information of the headmaster. Most schools and education bureaus will publish the principal's contact information, including telephone number and email address, on the official website.

2. Report to the education department that if there is a problem with the principal's education, you can report it to the local education department and ask for intervention. The education department will provide the principal's contact information and negotiation.
