The catering industry in Song Dynasty developed synchronously with the commodity economy, especially in big cities. In Kaifeng City at the end of the Northern Song Dynasty, "the house of street brokers often only buys food and drinks from the shops in the city, but ignores the vegetables at home". "The night market will not reopen until after midnight, and everything will be known if it is noisy." Although it snows heavily and rains in winter, there are also night markets.

Kaifeng is called Qibao Wuwei porridge, and Lin 'an is called Wuwei porridge. On the 25th day of the twelfth lunar month, the rice is like pearl beans. "Ginger slices and cinnamon poured with sucrose are smoother and sweeter than Huang Liang". ⑤ Peas, barley porridge, peas and jujube porridge eaten in the north, the latter should be millet porridge. ⑥ Glutinous rice food also includes chestnut jiaozi, cakes, bean balls, hemp balls, dumplings, water polo, sugar cakes, honey cakes, chestnut cakes and milk cakes.

Song dynasty hotpot. Lin Hong, a poet in the Song Dynasty, mentioned eating hot pot in Confessions of a Clear Mountain Residence, saying that he visited Wuyishan and made a rabbit to cook in the snow without a chef. "Shi Yun: Only a few batches are used in the mountains, and the wine, sauce and pepper are alive (soaked in oil). Put the stove on the table, use half a glass of water (half a bucket), wait for the soup to ring (after the soup is boiled), and divide the chopsticks, so that you can put it in the soup (rinse) and cook (eat), but you can provide juice at will (everyone can eat at will). " From the way of eating, it is similar to the current "rabbit hot pot".
