Call the contact number of the Education Bureau. Generally, the phone number of the Education Bureau will be transferred to the relevant person in charge's mobile phone or duty phone on weekends. After dialing the contact number, you can communicate your problem directly with the person in charge or the person on duty.

Send e-mail. Many education bureaus will arrange staff to be on duty on weekends. You can send an email to the official mailbox of the education bureau to explain the problem in detail. Generally speaking, the email reply speed on weekends may be slow, but the staff will handle it as soon as possible after going to work on Monday.
