Wow, CCB’s diamond credit card is so high-end. I went to the CCB credit card website and saw that the first and second among the "high-end products" on the page were their diamond credit cards. I clicked in and took a look. Select "Global Airline Business Travel Service" and there will be an introduction. I took a screenshot for you. According to what is written on it, you can use pp cards to enjoy services in more than 700 airport VIP lounges around the world. I want to Hong Kong There must be some. You see, there is a pp card URL on this website. You can go there and check out the corresponding airport VIP lounge.
