What does it mean for Alligator Dragon Dragon Cui members to upgrade their rooms for free?

Hello, free room upgrade is an exclusive discount offered by E Long. Longcui VIP Network. Longcui members can log in their accounts on the website and see the hotels that can enjoy upgraded room types (different hotels can enjoy different upgraded room types, for example, upgrading a standard room to a luxury standard room can enjoy low room rates and advanced room types).
