Is it serious to modify the date of health certificate?

Legal analysis: there is no special law to stipulate the punishment method of altering health certificate, but the altered health certificate is definitely not a valid health certificate.

Legal basis: Article 38 of the Regulations for the Implementation of Hygiene Management in Public Places in the State Council City, People's Republic of China (PRC), if a public place operator arranges employees who have not obtained valid health certificates to directly serve customers, the health administrative department of the local people's government at or above the county level shall order them to make corrections within a time limit, give them a warning and impose a fine of not less than 5,000 yuan in 500 yuan; If no correction is made within the time limit, a fine of not less than 5,000 yuan but not more than 15,000 yuan shall be imposed.
