Actually, even the gas tank can't be put down. For the sake of safety, food and drug supervision is not allowed.

If you have a catering business license, you must apply to the Food and Drug Administration for a food license.

Materials required for food license: business license, official seal, health certificate, copy of real estate license, rental contract, food system and application form.

Process: Submit the information-the food and drug supervision should conduct on-the-spot investigation-and issue a certificate after passing.

Checking your gas tank is to try not to buy more fire extinguishers if you can't get them out.
