"Food is not tired of essence, and grains are not tired of essence", which means that it is not too late to choose Gu Mi for the rice cooked by grains, and it is not too late to slice the grains made by the smell of cattle, sheep and fish. There is nothing wrong with carefully selecting rice and cutting rice and striving for perfection only in cooking skills. If it is extended to "sacrifice"-when making food for sacrifice, we should choose the best raw materials, process them as finely as possible, and show utmost forbearance. It should be said that it is also in line with Confucius' thought of paying attention to the "etiquette" of diet. "We have gained a little (profound and subtle) diet."

Regarding the principle of diet, that is, "eating classics", Confucius once put forward the famous "eight don't eat", that is, "if you eat glutinous rice, the fish will lose meat instead of eating it. Evil color, no food. Smelly, do not eat. No food, no food. From time to time, there is no food. Don't eat it if it's not cut properly. Without sauce, there is no food ... no food, no food. " The food has gone bad for a long time, the fish has gone bad, the drink has changed color, and the food smells rancid, so of course it can't be eaten. "Selling bartenders, not eating." Zhu explained in the Analects of Confucius: "Selling and the market are both buying. I'm afraid I'm not clean and I'm afraid I'll hurt someone. I agree not to taste Kangzi's medicine. " These principles of paying attention to food hygiene should be said to be instructive today.

The so-called "undercooked" means that the food is not cooked well and the festival of raw and cooked is lost-it is either undercooked or overcooked, which is of course not suitable for eating. Three meals a day, eating on time and in quantity all year round, is a eating habit that conforms to the growth law of fruits and vegetables. If you don't eat in time, you will be in trouble. Confucius also warned future generations: "Although there is a lot of meat, it does not make it better than eating gas." "Only wine is boundless and not chaotic." In short: when there are more meat and vegetables on the table that night, don't just eat meat and vegetables, so the amount of meat and vegetables you eat exceeds the amount of staple food. Although there is no need to limit the amount of alcohol you drink, you should also be moderate, and you should not get drunk or even lose your mind. These good eating habits are undoubtedly beneficial to "health".

According to the annotation in The Analects of Confucius, "If you don't cut it right, you won't eat it": "It means that if you break the animal's spine, flank and arm, you will be polite. If the anatomy is not correct, don't eat it. " Whether cutting meat is correct or not is required according to the dietary etiquette standards pursued by Confucianism. "Righteousness" is a ritual, and food does not hinder it; "Incorrect" is against etiquette, so it can't be eaten. In the same way, what kind of meat goes with what kind of seasoning is also particular. For example, Yi uses onion sauce in spring and mustard sauce in autumn, which is also required by Li. "No sauce", out of order, of course not. You can get a glimpse of the exquisite etiquette of China's food culture.

Around the food etiquette, Confucius not only put forward many requirements for the food itself, but also put forward many dining etiquette and rules, some of which are still of reference significance today. For example, attending a banquet, "If there is a banquet, it will change color." The host warmly treats the guests, and the guests will stand up to express their thanks in order to respect their personal feedback. If you have good wine and good food, you should be humble and invite your parents to dinner first to show filial piety. This is "there is wine and food, and my husband is delicious." "When the villagers drink, the staff will come out and they will go out." After the rural drinking ceremony, they have to wait until all the old people with sticks leave. Confucius also said, "Eat without words, sleep without words", eat without words, sleep without words. "Don't sit if the seat is not straight", don't sit if the seat is not straight and so on.
