The rich period of China's food culture is attributed to the exchange of Chinese and western food culture in Han Dynasty. Pomegranate, sesame, grape, walnut (i.e. walnut), watermelon, melon, cucumber, spinach, carrot, fennel, celery, lentils and alfalfa are mainly used for horse food, lettuce and lotus root, namely lettuce, green onion and garlic, and some cooking methods are also introduced. For example, in the Eastern Han Dynasty, Liu An, king of Huainan, invented tofu to make the nutrition of beans easy to digest. 1960, Miqi, Henan Province, found a large relief stone in the Han tomb, including the stone carving of tofu workshop. Vegetable oil was also invented in the Eastern Han Dynasty. Before that, animal oil was called grease, horned animal oil was called grease, and hornless animal oil was called ointment. The fat is hard and the paste is thin and soft. The vegetable oils include almond oil, shea butter and sesame oil, but they are rare. After the Northern and Southern Dynasties, the varieties of vegetable oil became cheaper.

There are strict regulations on the consumption of rice and vegetables, and the different grades are reflected in the food etiquette. For example, princes and nobles pay attention to' cattle should be steak, sheep should be millet, elephants should be straight, dogs should be beam, geese should be straight, fish should rise, and gentlemen should let them go every time they eat'. Cereals include rice, wheat, millet, millet, soybeans, red beans, pockmarked seeds and so on. Vegetables and fruits include mustard, sunflower, taro, ginger, bamboo shoots, lotus root, water chestnut, plum, bayberry, pear, persimmon, jujube, orange, loquat and melon. Meat food belongs to cattle, sheep, dogs, pigs, horses, rabbits, sika deer and other animals; Birds include chickens, pheasants, ducks, geese, partridges, quails, cranes, swans, turtledoves, snipes, mandarin ducks, bamboo chickens, fire-spotted chickens, owls, magpies and sparrows. Among the fish, there are carp, crucian carp, herring, hairtail, bonito and mandarin fish. In addition, there are eggs, various cakes and wine in the food and drinks buried with him. Seasonings used in cooking include salt, sauce, lobster sauce, sugar, honey, distiller's yeast, vinegar and so on. The daily diet of the poor is mainly bean rice and Tang Huo. "People generally eat bean rice and Tang Huo". There are more than twenty kinds of dishes. Every king eats 600, six animals, six clear drinks, 20 products for shame, eight things for treasure, and 20 altars for sauce. This tells us that the diet provided to the king should conform to certain moral norms. "Book of Rites * Book of Rites" said:' There are the heaviest people, six out of twenty beans of the son of heaven, two out of sixty princes, eight doctors and six doctors. The food ceremony of the folk civilians is' the gift of drinking in the countryside, 60 people have three beans, 70 people have four beans, 80 people have five beans, and 90 people have six beans, so it is also clear to support the elderly'. Drinking in the countryside is a ceremony for villagers to get together and drink at the right time. In this celebration, elders are the most respected.

Gifts come from diet, and at the same time, dietary activities are strictly restricted. Not only pay attention to food specifications, but also have rules for the placement of dishes. "Book of Rites * Quli" says:' When eating, you eat left and be right, the eater left and the soup right. Outside the cooking place, in the sauce-dredging place, onion slices are right, and wine paste is right. Those who abandon the custom of breasts are left behind, left behind. Translated into modern words, that is to say, whenever a simple meal is displayed, the dishes with bones are placed on the left and the cut pure meat is placed on the right. Dry food and vegetables are on people's left hand side and soup is on their right hand side. Fine-cut barbecue should be placed in the distance, and vinegar and sauce should be placed nearby. Steamed onions and other condiments are placed next to them, and drinks such as wine pulp and soup are also placed in the same direction. If you want to divide dried meat, breast meat, etc. It is curved on the left and straight on the right. This set of rules is also recorded in detail in the Book of Rites. When serving, take it with your right hand and your left hand; When serving fish dishes, if you cook fish, face the guests with the tail of the fish; In winter, the fish belly faces the right side of the guest, and in summer, the fish ridge faces the right side of the guest.

In the process of eating, there is also a set of red tape. "Book of Rites * Quli" contains:' If you don't have enough to eat together, don't choose your hands, don't argue for food, don't put rice, don't sing, don't eat, and don't bite your bones. No fishing, no throwing dog bones. No real harvest, no rice, no rice, no soup, no teeth. Guest flocculant soup, the owner can't cook. The guest apologized and the host resigned from the basket. It's better to submit to humiliation than to submit to humiliation inside. Don't worry. If the guest kneels before eating and comes down to take a picture after eating, the host will say goodbye to the guest and then the guest will sit down. The general idea of this passage is: when eating together, you shouldn't just eat yourself. If you eat with others, check whether your hands are clean. Don't rub rice balls with your hands, don't put extra rice in the pot, don't get your mouth wet, don't eat loudly, don't chew bones, don't put bitten fish back on plates and bowls, and don't throw meat bones to dogs. Don't stick to food, don't fan hot rice, eat rice with your hands instead of chopsticks, don't gulp soup, and don't mix vegetable soup in front of your host. Don't pick your teeth in public and don't drink dirty meat sauce.

If a guest is mixing soup, the host will apologize and say that this dish is not good to cook; If the guest drinks pickles, the host should also apologize and say that the prepared dishes are not enough. Wet and soft meat can be bitten off with your teeth and shared with your hands. When you eat barbecue, you should knead it into a handful. After eating, the guests should get up and clean up the popular dishes on the table and give them to the host waiting next to them. The host will get up and tell the guests not to work, and then the guests will sit down.
