What does unlisted hotel mean?

Unlisted hotels are hotels that have not been rated and listed, also called quasi-star hotels. At the end of 2004, the Beijing Municipal Tourism Bureau banned hotels from calling themselves "quasi-star hotels." There is a vivid metaphor for star reviews: star hotels are students who have obtained diplomas, non-star hotels are students who have not obtained diplomas, one-star hotels are students who have graduated from junior high school; two-star hotels are students who have graduated from technical secondary school; three-star hotels are students who have not obtained diplomas. University graduates; four-star graduates are postgraduate graduates; five-star graduates are doctoral graduates. Mr. Wei Xiaoan has a concise statement that summarizes the characteristics of one to five-star hotels: one-star hygiene, two-star friendliness, three-star comfort, four-star luxury, and five-star culture. Use the number and color of stars to indicate the level of the tourist hotel. The star rating is divided into five levels, namely one-star, two-star, three-star, four-star and five-star (including platinum five-star). The lowest is one star and the highest is platinum five stars. The higher the star rating, the higher the grade of the tourist hotel.
