Who knows the manners?

(1), sitting posture is suitable for the most formal occasions. This sitting posture requires that the upper body of the sitting person is at right angles to the thigh, thigh and calf, the calf is vertical to the ground, and the knees and feet are completely close together. This sitting posture is suitable for both men and women. Just be careful not to fill the chair in front of the elders, accounting for about 2/3. (2) The main requirements of the knee-hanging posture are the same as the previous posture, except that the knees are slightly separated, but they do not exceed the shoulder width. This style is suitable for both men and college boys. (3) Stretch forward and bend back, first put the thighs together, then stretch out one leg forward, and bend the other leg backward at the same time, with both feet on the ground, keeping a straight line before and after. (4) After sitting with your legs crossed, put your legs together and tilt your feet to the right or left at the same time. The angle with the ground is about 45 degrees, which is especially suitable for women wearing short skirts to sit in lower seats. We can often see from TV pictures that in diplomatic occasions, ladies and heads of state's wives in delegations of various countries all adopt such a sitting posture, giving people the impression of elegant posture. (5), feet crossed knees together, feet crossed at the ankle, but not too far, this type can be used by both men and women.
