Chinese people are used to turning joys, sorrows and joys in life, weddings and funerals, and socializing into eating activities. As the so-called "reciprocity of etiquette" improves the relationship between people, the style of banquets and parties has greatly developed. People closely connect diet and social interaction, and the matter of diet is devoted to the expectation of family harmony, state governance, and world peace. Through banquets, people not only enjoy the art of food, but also enhance affinity and achieve harmony.
