Can anyone introduce some Vietnamese etiquette

Men in Vietnamese cities tend to wear suits and women wear flowery narrow-sleeved robes. Vietnamese women's robes can be said to be the national costume of Vietnamese women, with a girdle at the top to emphasize the body and make the woman look shapely, and a stretchy hemline with a slit up to the waistline for easy movement. Special attention is paid to the fact that Vietnamese women also wear a pair of black or white wide-legged floor-length pants when they wear the robe. Vietnamese women like to wear necklaces, bracelets and rings, and tend to wear their hair in long shawls or tied behind their heads with hairpins.

Vietnamese people are very polite. When they see each other, they greet each other or nod their heads. To elders, they call them big father, big mother or uncle, to equals, they call them brother and sister, to children, they call them little brother and sister, and to the masses, they call them folks, fathers, and compatriots (used only between nationals). The Kinh do not like people to clap their hands on their backs or point their fingers at them and call out to them. When outsiders come to their homes, they cannot use their feet to point at things, they cannot use their feet against people when sitting on the floor, they cannot cross over people who are sitting or lying down, they cannot sleep at the door of a woman's room or in the aisle where they often come and go, and they are not allowed to enter the master's inner room. In the homes of ethnic minorities, it is absolutely forbidden to go into the room where the girl lives. Some ethnic minorities live in bamboo and wooden houses and are used to sitting and lying on the upper floors. Into the house to take off their shoes, otherwise it is considered to look down on the host. Young people have special respect for the elderly. In the northern Jing family, by the oldest generation of men in charge, the southern Jing by the oldest generation of women in charge, everything generally have to seek their views, as long as they agree to things, others generally will not express dissent. And the elderly peer, such as to go over, should be greeted first, said the first step. In ethnic minority areas also have the habit of honoring the elderly, such as the Dai, the Luo family has a stool exclusively for the elderly to sit, young people and outsiders are not allowed to sit.

Some ethnic minorities are very hospitable. Guests come to their homes, commonly used in the nation's favorite wine and love to eat cold, sour and spicy food to treat the guests. Therefore, even if the guests are not appetizing, they have to eat as much as they can, otherwise they will be regarded as looking down on their hosts. Ethnic minorities in the mountainous areas of the south, like to invite guests to drink altar wine together during festivals and celebrations, i.e., take turns to suck wine from the altar with a pipe to drink, and the first round (i.e., take turns to suck the first mouth) can't be refused, or else it is considered to be a spoilsport and a breach of etiquette. After the first round, if you don't want to drink, raise your hands to your right shoulder to show your thanks for not drinking anymore (this is also done during meals).

Vietnamese people like to chew betel nut, people usually use reed leaves wrapped in some ash or inkstone ash, with betel nut together with the entrance, ash and betel nut will have a chemical reaction, the taste of chewing betel nut began to be bitter, then sweet, and have a stimulating effect on the nerves. Betel nut is also a local gift for lovers.

Don't touch other people's heads, including children. When there is a green branch hanging at the village intersection, it is a sign that entry is forbidden and outsiders are not allowed to enter. The Khmer Krom people in the south abstain from saluting, eating, giving and receiving things with the left hand. Vietnamese taboo three people together, can not use a match or lighter to three people in a row to light a cigarette, considered unlucky.
