I plan to travel to Hong Kong and buy gold ornaments for my wedding, such as rings, necklaces and earrings.

Large chain stores: Zhou Shengsheng, Chow Tai Fook and Luk Fook Jewelry.

3 it is not recommended to use RMB directly and swipe your card.

A lot.

All shops in Hong Kong can set prices freely as long as they are clearly marked. In other words, the exchange rate may be different from place to place, depending on the location and business of the store. Theoretically, the price of each house may be different, so it is best to change the necessary amount of Hong Kong dollars in domestic banks first.

As long as there are many mainland tourists and big chains, Hong Kong can accept UnionPay. On the contrary, many restaurants accept international credit cards, but not UnionPay.

Blww44' s statement is a general description and inaccurate. If your dual-currency credit card is USD and RMB, there are indeed two exchanges of HK$-USD-RMB at the time of repayment. Then, since RMB has always been in the same direction in recent years, the later it is exchanged, the more foreign currencies can obviously be exchanged. Generally speaking, it can offset exchange losses. Secondly, POS machines in many shops in Hong Kong allow you to choose US dollars or Hong Kong dollars on the spot. If you choose USD, you only need to change it once when you go back (assuming that you repay in RMB). Moreover, if your dual-currency card itself is Hong Kong dollars and RMB, there is no problem. UnionPay uses the exchange rate of UnionPay on the same day, which is generally better than the exchange shop, and the RMB is deducted on the spot. However, if the RMB exchange rate remains unchanged and is roughly flat on the repayment date, it will not be worthwhile for the RMB to appreciate again. In Hong Kong, credit card organizations often have different discounts with specific merchants, so it is best to have UnionPay and Visa/Master at the same time, which is more cost-effective.

In addition, it is best to have Octopus in Hong Kong, which is convenient to take the subway bus. In addition, convenience stores also accept Octopus to avoid the trouble of change.

If you are in customs clearance places such as Luohu, you must have Hong Kong dollars to buy Octopus, otherwise it will be chopped up on the spot.
