Confucius (55 BC/KLOC-0 BC/-479 BC), the founder of China's diet theory, was named Zhong Ni. At the end of the Spring and Autumn Period, Confucius was from Changping Township (now southeast of Qufu, Shandong Province). He was a famous thinker, educator and founder of Confucianism in ancient China. According to legend, 72 disciples led his disciples around the world 14 years. Confucius was also an ancient literature collator, who wrote poems and books, made rituals and music, and made a preface. Confucius was noble and upright, optimistic and enterprising, and pursued truth, goodness and beauty and an ideal society all his life. His thoughts and theories had a far-reaching impact on later generations. Confucius' dietary thoughts and principles are mainly embodied in The Analects of Confucius and The Rural Party, which are summarized as "two tireless, three moderate and ten abstinence". Later, Mencius inherited and developed them, which became the theoretical basis of the "Confucius-Mencius esophagus" of Chinese national food culture. Confucius' dietary thought is a systematic proposition about diet summarized and expounded on the basis of summing up historical experience. As a philosopher and thinker, Confucius observed the social phenomenon of food life from a strategically advantageous position, deeply thought and studied the historical development of food culture, and his attitude and proposition on food life as a lofty idealist and pure ethicist. Confucius's "way of eating", the most widely known and representative of which is the word "never tired of eating, never tired of eating". Confucius' dietary life and thoughts can be summarized in four words: simplicity and simplicity. He abides by the principles of "a gentleman seeks the Tao without seeking food", "he worries about the Tao without worrying about poverty" and "a gentleman wants to eat but is not satisfied, and a villain wants to be safe and uneasy". In the 5,000-year history of China, Confucius had a great influence on the character and temperament of the Chinese nation. Now the poem praises it: the most sacred symbol includes the township party, and the history of Taoism and food is detailed. The doctrine of the mean is self-discipline by virtue, and it takes health care to hurt the body. Three people can talk about the doctrine of the mean, and those who keep the Ten Commandments are forbidden. It is great that future generations never tire of making mistakes for a long time and that justice has been honored. Note: 1, Confucius' food speech and thought records are scattered in pre-Qin classics, and the most concentrated ones are The Analects of Confucius and The Rural Party. 2. Confucius advocated that "a gentleman seeks the Tao but not the potential" (The Analects of Confucius, Wei Linggong), and that "a gentleman does not have enough to eat and is restless" (The Analects of Confucius, Learning and Thinking) values the food of others and ignores his own food; It is believed that a gentleman should take perfecting moral cultivation and exploring the laws of the world as his unremitting pursuit all his life, should take public morality as the people and oppose indulging in personal material desires. 3. Confucius' view on the principle of sacrificing food in The Analects of Confucius and the Rural Party is summarized as "two are not tired, three are moderate, and ten don't eat" in the textbook. 4. In the two thousand years after Confucius, the discussion of "two is not strict, three is moderate, and ten is not greasy" has been shrouded in various misunderstandings, especially the misunderstanding of "food is not greasy, food is not greasy".
