A "gourmet" is a gourmet who takes a wide range of foods as objects, that is, the real food in the sense of "diet", not just "food"-a professional who tastes and appreciates dishes in a narrow sense and pasta, cakes and so on. Unlike gourmets whose job is to fill their stomachs and those whose purpose is to explain the esophagus and food theory, gourmets are people who appreciate food from art and aesthetics with a happy attitude towards life and engage in the exploration of ideal food. The main purpose of gluttons is to pursue and satisfy material desires, while gourmets focus on understanding and theoretical induction. Gourmets not only have rich and vivid food practice and material enjoyment, but also have profound and unique experience and artistic consciousness. They are the explorers and creators of the beauty of diet life in which matter and spirit, physiology and psychology live in harmony. There are countless gourmets in the history of China-most of them belong to this category, and there are many gourmets, but few people can really be called gourmets. "People don't know the taste until they eat it" (Book of Rites, The Doctrine of the Mean, Volume 31, Volume 52), which is true. Of course, this does not mean how successful a grain grower is, nor does it mean how unattainable a gourmet's job or business is. The fact is simple: "the knower has passed, but the fool has not"; Or "people who go up and down the beach" have passed, and they are not as unscrupulous as they are. "(The Book of Rites, The Doctrine of the Mean, Volume 52) Those with high intellectual interest are not here, but lightly! In the era when Confucius and Mencius' thought of food restriction dominated social concepts, the dietary behavior of the upper class often deviated from its dietary remarks. How can we expect those "knowledgeable" and "intelligent" people to take care of this matter? By the same token, those who are "fools" and "unworthy" are of course incompetent because of economic poverty or poor education, and once they are expected to surpass the boundary of "knowing only above and being foolish below" set by saints or social obstacles (The Analects of Yang Huo, Volume XVII), they will all rise to the status of "knowing" and "saints" without exception.
