Tip: If any part of your body is aching or in pain (of mascular nature), just rub that affected area with this oval shape bianstone. It is as good as acupuncture, but without the pain of the needle. It is better than guasha, without applying any oil. During dry weather, you can dip into warm/hot water before applying the bianstone on your body.
