I would like to ask how Chinese medicine regulates the stomach and how to gain weight.

Have a full meal and eat high-calorie foods such as fried, puffed and cream. Have some cake in the evening. When you go to bed at midnight, you should drink a glass of milk and be full of fat (which can help you sleep and gain weight). After lunch, take a nap. In short, as long as you are full, you should keep a good mood, but you can't just sit back and wait. As the saying goes, we should also be broad-minded and fat.
