Sit on the bed or sofa, bend your legs naturally, so that your calves are in the most natural state of relaxation, and then shave from your knees to your heels for 20 minutes every day (or stroke your left and right legs 100). Scrape down from the knee bend. You can only scrape in one direction at a time, not back and forth like taking a bath. I hope my answer can help you and be adopted!
