What do you mean by hanging three hotels?

the abbreviation of the listed three-star hotel is the official three-star hotel that has been approved by the Star Rating Committee of the National Tourism Administration and awarded the plaque of the three-star tourist hotel. Other hotels have just opened (the star rating can only be evaluated after the hotel has opened for a period of time), or most of the software and hardware standards have reached the three-star standard, but some conditions have not been met and failed to pass the three-star rating. Some hotels that have reached the three-star standard and exist in the name of some enterprises and institutions' guest houses and training centers generally do not participate in the star rating, and they are all known as three-star hotels.
