你好，朋友！
Seated posture, foot in my seat, can not arbitrary straight, elbows should not rely on table edge, or hand on the back of a chair next to him. Table must be gentle, quiet and calm, can not be impatient. On the table can be selfish, but also to care for others, especially on both sides of the greeting of the ladies. The mouth of food, should avoid to speak.
希望能帮到您！
