You need to return the registration number one day in advance (depending on the time for returning the registration number) ... You need to return the registration number in time ... If no one helps you get the registration in the hospital after the time for returning the registration (if you want to get the registration card, you can get the registration without seeing a doctor), then even if you break the contract once, you can't make an appointment in this hospital for a certain number of times, such as blacklisting.
