Why don't chain hotels have stars?

The word chain hotel can be said to be a new synonym. Why can't we judge the stars? It's because the business projects she provides don't meet the hotel star standard stipulated by the Tourism Bureau. The basic conditions that a star-rated hotel must have, such as the number and size of rooms. The scale of catering business premises and reception scale. Entertainment facilities, fitness equipment, business center, western restaurant, etc. Chain hotels generally only have the functions of accommodation and breakfast, and some don't even provide breakfast, and the room size is not standardized. There are no other evaluation criteria. Moreover, the name "hotel" is not necessarily set according to the relevant standards of the Tourism Bureau. However, the current market demand is diversified, and I believe there will be relevant evaluation standards.
