Fengqing Huang Chao Foot Massage is a famous foot massage club. As far as I know, it is legally operated and conforms to the relevant business code of conduct and hygiene standards. However, the specific degree of formality may vary according to the region and the operation of specific stores. To judge whether a foot bath shop is formal, I suggest you pay attention to the following points when choosing:

1. Business license and related qualifications: Regular foot bath shops should hold valid business licenses and business license certificates, which can be used as an important basis for judgment.

2. Sanitary environment and facilities: A regular foot bath shop should have a good sanitary environment, including clean and tidy work areas and equipment, clean and hygienic sheets and towels.

3. Professional technical team: A regular foot bath shop should have a team of professionally trained technicians who can provide professional foot massage care services to ensure safety and effectiveness.

4. Price transparency: Regular foot bath shops usually provide clear service prices and service contents, and there are no hidden charges.

Generally speaking, foot massage in the Qing Dynasty can be considered as a regular foot bath shop if it has the above characteristics. But the specific situation needs to be understood and judged by yourself.
