You can get a discount. I have a Chow Tai Fook star membership card. I can get 30% off the metalworking fee, 8.8% off the ctf2 series and 9.5% off the diamond ring. The card number is 6555 10. Ms. mou. All Chow Tai Fook stores in China can use it. Just report the card number before buying. Hong Kong, Macao and Taiwan cannot be used. You will save money and help me get membership points. Ha ha. I hope it helps you. Some netizens have used it, which is very easy to use.
