In addition to being stamped, the childcare provider’s certificate must also be stamped with the steel seal of the relevant department. In addition, it can be found on the website based on the certificate number above.

In addition, for further verification, you can check whether the housekeeping company has training qualifications, registration information, business license, etc.
