Confucius is a master of Confucianism, with rich experience, insight into local conditions and customs, profound observation of the way of eating and drinking, and delicate appreciation. He systematically summed up people's experience in diet and health preservation. He put forward a series of health-preserving ideas, such as "although there is more meat, it is not better than eating", "don't talk when sleeping", "don't eat too much", "only drink too much, so as not to be chaotic" and "eat less vegetable soup".
