Your question is very bad.

What are the benefits of star rating?

The same room

The decoration is the same.

One night in a four-star hotel in 400 yuan.

600 a night in a five-star hotel

A high star rating means better service, better hygiene, better environment, higher popularity, higher salary, more beautiful women, more money, more tips, more expensive meals, more important people, more luxury cars, more facilities and equipment, and the poor can't afford to live better.

The five-star ZF often goes to the conference hall for meetings.
