What should I pay attention to when I plan to travel to Shenzhen, Hong Kong and Macao in March and April? We went with two people in their sixties and didn't join the group.

1, the weather is no longer freezing in March and April, which is very comfortable. Generally, an underwear is similar to a coat.

You need a pass to go to Hong Kong and Macao. You need to get the above documents in advance.

I don't know where you are from. Except for Guangdong province, only some cities have individual tourist visas, and others are group visas. It's different now. In the past, teams could go through any travel agency in the port, but now they can't. You need to declare 48 hours in advance, so you need to find a tour group to declare for you 48 hours before you go to Hong Kong.

As for currency, you can change some Hong Kong dollars. I haven't been to Macao. You can change money in the bank before you leave. If you don't change it, it's very simple. You don't know if there is a dual-currency credit card. If you spend money in Hong Kong, you can swipe your card to take UnionPay. When you repay, your credit card will become RMB, so you don't have to worry about how to repay Hong Kong dollars. Also, you can use RMB if you don't change it, but it's not cost-effective for you (some people don't accept it). There are many places to change money in Hong Kong, but I suggest you change it at the port. It's safer to change at the subway station in the port. In other words, it is basically 0.8: 1, which is almost the same.

It's expensive to take the subway. Octopus is sold in the subway station in the port, but a deposit of HK$ 50 is required.
