If hotel guests are unwilling to open the door, can they be forced to enter?

This situation cannot be forcibly entered.

The guest room belongs to the guest's private space during the rental period. Breaking in without permission is an invasion of privacy. Customers pay the room fee and check into the hotel, which has formed a contractual relationship. This contractual relationship requires the hotel to provide corresponding services to the guests, such as providing a good living environment and ensuring personal and property safety, including cleaning services, of course. It also includes that guests can stay there without being disturbed.

According to Articles 38 and 39 of the "Constitution of the People's Republic of China", the personal dignity of citizens of the People's Republic of China shall not be violated. It is prohibited to use any method to insult, slander or falsely accuse citizens. The homes of citizens of the People's Republic of China are inviolable. Illegal searches or illegal intrusions into citizens' homes are prohibited.

Police officers can enter by force if they are required to perform official duties.
