"Simple tea and light rice" comes from Su Dongpo's Huanxisha. The drizzle and the setting sun make the dusk sad. The original text is: "The taste of the world is pure joy." Meaning: The happiest things on earth are light home cooking and simple vegetables and fruits. The lightness here does not mean the simplicity and inferiority of dishes, but an elegant and exquisite food artistic conception. "Bare tea and light rice" is a life attitude, a plain and natural life concept and an understanding of the true meaning of life. In this world, it is impossible not to eat fireworks, and it is also impossible to eat good food, wine and delicacies. Eating too much will hurt the spleen and stomach, and eating too little will make you hungry. Only by eating properly can we satisfy our appetite and not increase the burden on our stomach, so as to achieve the goal of health and longevity.
