During the Wei, Jin, Southern and Northern Dynasties, an important symbol of the development of China's food culture was the emergence of a number of food monographs. According to historical records, there are Cui Shi's Food Classics, Food Classics, Food Times Law, Four Seasons Imperial Food Classics, Ma Wan Food Classics, Tang Qiang Law and so on. Compared with the pre-Qin period, there is only one original flavor, which has made obvious progress.
