What does it mean to postpone the holiday of health certificate?

Refers to the two working days after the holiday adjustment and the extension of the Spring Festival holiday. Personnel engaged in catering services must hold health certificates, and there is a large flow of people on holidays. Institutions that issue health certificates will close down on legal holidays, resulting in employees not being able to take up their posts without health certificates. Therefore, the postponement of the health certificate holiday means that the service personnel can receive the health certificate within the adjusted working days.
