What are the standards for unlisted 4-star hotels?

Unlisted four-star hotels refer to hotels whose facilities meet the standards of four-star hotels, but have not been evaluated by the National Tourism Administration. At present, some hotel projects have not reached the four-star standard and are not eligible for application. The listing of four-star hotels has been reviewed by the tourism authorities for some time. The hardware and software facilities have reached the four-star service standard, but the new hotel must be operated for one year before applying.
