Recently, there has been a situation where the website needs to be shut down during the filing period. This is a requirement of the provincial communication administrations:
When filing a domain name without a registration number (only for a newly registered domain name and a domain name that has been registered but whose registration number has been cancelled), the domain name needs to be in an inaccessible state. If it is accessible, it will be rejected by the SAA, and the site will be closed before submitting it for the record. That is to say: such users need to file for the record first, and then go to the top-level domain name after the record is passed.
