1. When eating, the upper arm and back should lean against the back of the chair, and the abdomen and table should keep a distance of about one fist. It is best to avoid sitting with your feet crossed.
2. The napkin can be opened before eating. After ordering, open the napkin before the appetizer is delivered, fold it in by one third, and let two thirds spread flat on the legs to cover the legs above the knees. It's best not to stuff napkins into the neckline.
3. You can't suck the soup. Scoop the soup from back to front with a spoon, and put the bottom of the spoon at the position of the lower lip to send the soup into the mouth. The angle between the spoon and the mouth is preferably 45. The upper half of the body leans forward slightly. There is not much soup left in the bowl, so you can raise the bowl slightly with your fingers. If the soup is packed in a bowl with a grip ring, you can directly hold the grip ring and drink it.
Extended information
Through the earliest observation of western food by China people, we can see the difference of catering concepts between Chinese food and western food. The concept of catering in agricultural society, the bottom people, "food is the most important thing for the people", the highest realm of life is to eat a full stomach; Entering the upper class, the highest level of catering concept is to feast one's eyes and eyes, "never tire of eating refined food", and regard catering as spiritual enjoyment.
Westerners' catering follows the living habits of industrial society, and more importantly, it reflects the social hierarchy in catering. The attribution of social class here is not entirely the attribution of production relations, but also the attribution of spiritual class.
