It's a classic saying, "Hark for radish for winter, no medicine for Mr." It means that we should eat more radish in cold winters, that the rest of the world is colder in winter, that the weather is dry, that most people like to eat some of the fed foods during this season to increase the heat in their bodies, that radishs are cool foods, that they can detoxify, that they can cough, etc., and that proper eating of the radish can balance the heat in the body and thus feed. When I came to Beijing and found that the northerners preferred to eat alive, they said it was healthier and nutritious, that they could not accept the taste of the carrots at first, that they stayed with their friends for a long time, that they were not as bad as they thought, and that they were better if the spices were processed. When the pickled soybeans were finished the other day and the fresh pickled pickles were not ready to eat for a while, it suddenly came to mind that there was a white carrot in the house and the problem of eating pickles was solved after a few hours in the vinegar。
