How to upgrade the guest room of China Residence Association?

Gold members of China Accommodation Club can upgrade their rooms when they check into the hotel. The guest is a gold card member of the China Living Club, so when checking in at the hotel, the front desk staff can query the guest's membership information from the system. If you are confirmed as a gold card member, you will be upgraded to a higher level room for free on the basis of the room booked by the guest at that time. If the guest has booked the highest level room, then the member can get a certain member courtesy compensation gift equivalent to the difference of the upgraded room.
