What does scraping mean?

It is normal to produce sha after scraping, but it is also normal to have no sha or to have difficulty producing sha. These all appear based on physical constitution. According to Western medicine, the subcutaneous capillaries are broken and bleed due to external force. It doesn’t matter how the sha is explained. What is important is the pattern of sha every time you get it. Your physical condition can be judged based on the speed and color of the sha. How quickly the scraped sha fades away is determined by the body's metabolic cycle. The purple or black colors that appear on your body are caused by your physical constitution. You cannot judge your physical constitution by color alone. If you could know the speed at which the sha appears, or the specific circumstances at the time, you would be able to immediately determine your physical constitution.
