A friend of mine asked his boss to get a health certificate after leaving his job, and the boss deliberately lost the health certificate. What about this? These people are really hateful.

Let's just say it's not too much trouble. You can ask your friend to call the Food and Drug Administration to report his sanitary environment, operation process, improper treatment measures for unqualified products, imported raw and auxiliary materials that do not meet the relevant state regulations, and no inspection and quarantine certificate. Anyone who only needs the Food and Drug Administration to come once is not enough.
