The business license is the certificate that authorizes the operator to engage in legal business. It is strictly forbidden to rent, lend or transfer the business license. If you violate it, you will be fined by the industrial and commercial department. If the operator changes, it needs to re-apply to the industrial and commercial department; Tobacco certificates, local tax certificates and other documents can only be handled in accordance with the business license, so once the business license expires, other documents need to be handled again.
