Moreover, we should know that in Vietnam, people of the same age can't be addressed by Mr., Ms. and Master, let alone by Big Brother and Big Sister, but by Second Brother and Second Sister. This is because they have their own taboos. So before you go, you must be clear, you must do a good job of raiders, and you must pay attention to this information.
Moreover, Vietnamese people are forbidden to speak loudly and shout at each other with their fingers, which is a sign of disrespect for people. This is very impolite behavior in China, and people use toilet paper in China. Many people will be very disgusted with this kind of thing and will ignore you.
Moreover, Vietnamese people are forbidden to point their toes or feet at others, which they consider insulting. Moreover, the Vietnamese diet is relatively light, mostly boiled, fried or barbecued. So if we travel, our skin may become very good, and we may lose weight.
Besides, in the homes of ethnic minorities, you must never go to girls' rooms. Besides, we have to take off our shoes when washing upstairs, otherwise people will think that you look down on your master. Therefore, when we travel to another place, we must pay more attention to the customs of each place, otherwise we will accidentally touch other people's taboos, so don't blame others for not being enthusiastic about you.
