What is the mid-range check-in gift certificate in China-ASEAN Expo?

Sorry, I don't know the specific information of the mid-range check-in gift certificate in China-ASEAN Expo. But I can tell you something about the China-ASEAN Expo Diamond Card.

Dongcheng Hui Diamond Card check-in voucher is a high-end courtesy provided by Dongcheng Hui Hotel Management Group, and customers who hold this voucher can enjoy the advanced treatment of the hotel. In addition, they can use the executive floor of the hotel to hold small meetings and enjoy Chinese food for free.

If you need more accurate and specific information, I suggest you contact Dongcheng Hotel Management Group directly, and they will be able to provide you with the accurate and detailed information you need.
