Do not label the tea soup in the tea shop. Judging from the relevant public information, there are no laws and regulations that require homemade drinks to be labeled, but the operators of homemade drinks need food business licenses. Tea shops, as catering service operators, should formulate and implement food safety knowledge training programs for employees in order to avoid claims and complaints, organize and study food safety knowledge such as food safety laws, regulations, rules, norms, standards and processing operation procedures, and strengthen honesty and law-abiding operation and professional ethics education.
