2. Go to the on-site consultation: If the appointment time has not yet arrived and it is close to Tiananmen Square, you can go to the on-site consultation office of Tiananmen Square or the relevant office to explain the situation to the staff, bring the correct personal identification and ask if it can be revised.
3. Re-make an appointment: If the above two methods can't solve the problem, you can consider re-making an appointment to ensure that you fill in the correct personal information.
