Which side of the chair should I sit on when eating western food?

The most appropriate way to sit in a restaurant is to sit on the left. When the chair is opened, the body will stand up straight at a distance that almost touches the table. The leader pushes the chair in, and the legs bend and touch the chair behind, so you can sit down. After sitting, sit upright, and your upper body can lean on the back of the chair. Don't put your cheeks or elbows on the table with your hands. Don't often leave the table or move your seat. When eating, your upper arms and back should lean on the back of the chair, and your abdomen should keep a fist distance from the table. It is best to avoid sitting with your feet crossed.
