Dr China likes to say that "your kitchen is your pharmacy", which means that all vegetables are used for health preservation. In the past, in Hong Kong, whenever there was a typhoon or rainy season, the lettuce fields in the New Territories were flooded, and the supply of vegetables in the Hong Kong Island vegetable market decreased the next day, and the price of vegetables rose immediately. At this time, housewives will think of buying fruits instead of vegetables. It is always the chef who has a headache. When there is a typhoon, it is inevitable to cut off vegetables for two or three days, so we have to use the most reliable substitutes tomatoes and bean sprouts. Besides Yi Shu's novels, the best-selling books in bookstores are hardcover books that teach people how to distinguish vegetables from fresh fruits, light-colored vegetables from bulbs, so that you can eat a little bud, a little leaf, a little root and a little fruit every day. Let the body have saponin, protein, calcium and phosphorus, vitamins and citrulline.
