I want to travel to Hanoi, Vietnam. How much should I bring? Where can I exchange money?

First of all, I don't know if you travel a lot. I must remind you that Vietnamese locals like to cheat foreigners, especially those who travel. Liars can be said to be everywhere. If you're not cheated, it's okay to spend 3000 yuan for a few days. But if, it's hard to say. Remember to go to the bank to change money when you go to Vietnam, and you must have a lot of change in your pocket (because it is easy to get robbed when you spend money on several people, such as getting off by taxi, and you give all the money, and the taxi driver may run away without giving you change. ) There are many rickshaws in Vietnam Street, so don't sit. . .
