The hotel star rating is divided into five levels, namely one-star, two-star, three-star, four-star and five-star. The higher the star rating, the higher the grade. The classification is also based on the hotel's architecture, decoration, facilities and equipment, management, and service levels. The specific assessment method must be submitted by the legal person of the hotel to the Tourism Bureau for star rating, and shall be implemented and reviewed in accordance with the facilities and equipment assessment standards, facility and equipment maintenance assessment standards, cleanliness assessment standards, guest opinion assessment standards, etc. issued by the National Tourism Administration.
