You can also choose the credit card of Bank of Communications. Bank of Communications' credit card has a special discount in Hong Kong, and if you go shopping on holidays, many shopping malls can enjoy more discounts by swiping Bank of Communications' credit card, which is not very cost-effective.
In addition, if the Bank of Communications Gold Card reaches the maximum consumption limit in Hong Kong, Macao and Taiwan, it can give points up to 500,000. This looks very exciting, so it is more cost-effective to choose the card of Bank of Communications, and shopping can save a lot of money.
