If you want to travel to Vietnam, what currency is circulating in Vietnam?

Vietnamese dong, banks can exchange US dollars, hotels and general tourist places in big cities accept US dollars, and places with a large population in China, such as Nha Trang and Da Nang, also accept RMB, and a few places can pay by WeChat and Alipay.

It is suggested that after you bring US dollars, you can change Vietnamese dong in the bank (banks can't change RMB), or you can change money in the gold shop (where gold is sold). The exchange rate is better. And most places can be swiped, domestic credit cards and UnionPay cards can be swiped, and ATMs can also use UnionPay cards to withdraw cash directly. The handling fee is a little more expensive. The withdrawal rate of domestic banks+the local service fee in Vietnam is about 3 RMB for ABC, and only 12 RMB for Huaxia Card.
