Check whether the hygiene license is true or false. The specific methods are as follows:

1. Log on to the official website of the State Food and Drug Administration, and you can search in the search engine or inquire about its local branches.

2. I saw a navigation of "data quick check" on the home page, but there is only drug query here. For more classifications, click "Public Query" or "Professional Query" in "Data Query" on the navigation bar.

3. on the page of "public inquiry", you can click "combined inquiry", which contains more inquiry conditions. First, select the category, and if it is a food enterprise, select "health food", and then fill in the key words such as enterprise name and batch number.

4. The catalogue in "Professional Inquiry" is more detailed. Click on the catalogue to be inquired. If the enterprise to be inquired is a food producer, select the first "enterprise with food production license".

5. Enter relevant information and click the query button. Note that "food" and "health food" are distinguished here.

6. Click the link of the inquired enterprise information, read the specific information of the enterprise and products, and check the ID number. If it is not found, please check whether the information entered is wrong. If it is correct, the information is false.
