Unless you are invited as a guest to a tent or house, you are to remember not to step on the threshold of the door. When calling someone, you will add "La" behind his or her name to show respect. When you are asked by the host to take a seat, you should sit cross-legged and don't stretch your legs with your feet pointing to the other. If someone gives you gifts, you should receive with both hands. When presenting gifts to someone, you'll bend your waist and lift up the gifts in both hands over your head to show respect. When you are offering tea, wine and cigarettes to someone, you are to offer them with both hands and don't let your finger into the cup.
