It's very cold in March and September, so keep your head warm and remember to wear a hat when you go out. Because the head is the nerve center of the human body, and the head is the intersection of all yang meridians, all yang meridians reach the head.

In addition to the head, the warmth of the abdomen can reduce diseases such as abdominal pain and diarrhea caused by cold, and the warmth of the knees is also very important. It is not advisable to expose your knees too much for the sake of beauty. Besides wearing thick shoes and socks, you can also soak your feet with hot water.
