The third floor is the second floor of the restaurant. The reason why the dental clinic can't be opened is because of health and safety problems, because the dining place will produce pollution such as lampblack and noise, which will have a bad impact on the environment of the dental clinic and is not conducive to the treatment and rehabilitation of patients.

In order to ensure the health and medical safety of patients, the dental clinic needs to be set in a relatively quiet place with good sanitary conditions, and keep a certain distance from other commercial places such as restaurants.
