Do I have to take 3000 cash to Vietnam?

You don't have to bring 3000 cash to go there.

Domestic travel agencies have reminded passengers going to Vietnam to bring 3000 yuan in cash each, saying that it is to cope with customs spot checks. However, when they actually entered the country, no one could find out. On the contrary, you can swipe your card in large amounts, so tourists are advised not to bring so much cash, and at the same time you can avoid the embarrassment of being randomly selected.

In addition, Vietnamese customs used to ask China people for tips, and carrying too much cash may increase the risk of getting into trouble.
