Will the police visit the four-star hotel?

Yes.

The police will also visit four-star hotels. No matter what star the hotel is, the police will conduct rounds. But relatively speaking, the police will go to four-star and five-star hotels to check the rooms. The times will be few.

The basic standards for a four-star hotel are that a four-star hotel must have central air conditioning, a background music system, and 18-hour foreign currency exchange services. The four-star hotel must have at least 40 rooms available for rent, and 70 % of the guest room area, etc.
