Different places need different scraping methods. If you shave your face and lie flat before going to bed, separated by a layer of pajamas, it is best to choose buttonless pajamas. Holding the scraping board in one hand, push it about 10 times from the stomach to the middle of the pubic symphysis of the lower abdomen, and then do it several times from the middle to the left and right, in order from top to bottom.

If you scrape the side, you need to scrape the front side first and then the side ribs, from top to bottom, all the way to the waist, and when you reach the edge of ilium, it just falls on the vein, and both sides are scraped about 10 times. The next step is to scrape the veins on both sides, starting from the middle of the lower back, moving from top to bottom according to the vein area with a scraper, reaching the abdomen and finally landing on the pubic symphysis. Repeat this for about 10 times, and then if you go out to do the other side, don't worry, just stop and do it again in the same way the next morning, about ten minutes.
