For the past 30 years, the Chinese government has gradually established an fairly effective hotel star rating system which has classified all qualified hotels in China into five categories - Five Star, Four Star, Three Star, Two Star and One Star ( or youth hostels). The higher level of a hotel's star rating system, the better service and high rates you will expect. But The number of stars of a hotel may not necessarily match its service level.

5 Star Hotel
The 5 star hotels in China will offer you a good night stay with full range of moden room facilities. But the hotel rates are also very expensive usually ranging from USD100 to USD500 per room per night. 

4 Star Hotel
You will feel very comfortable for most of the 4-star hotels in China. but some 4 star hotels are far below your expectation and you would like to stay in a clean and cozy three star hotel.

3 Star Hotel
There is a big difference between the quality among the three star hotels in China. The three star hotel rating is decided by the local governments with strong local protectionism. Some of the three star hotels are clean and comfortable; some are just rundown and shabby. Most of the three star hotels have no websites which make it quite difficult to book online. 

2 Star Hotel
Strangely enough, 2 star hotels have comfortable facilities comparable to some 3-stars. But the problem for many 2 star hotels is that very few staffers can speak English. So if you are able to manage it, you may get some good rates.

One Star or Youth Hostel
Youth hostes are getting very popular in China. Low rates with simple and basic facilities. The rooms are clean and safe too. The staffers are always helpful and resourceful. Most of the staffers at youth hostels can speak English.
