While doing the ear massage myself, I felt oil on the forehead, the triangle, etc., and I thought there must be something wrong with that part. Touching his ears gives him some sense of security...The problem is, I don't know about other people, but I don't do it often because it's hard to do it myself. ㅠㅠ And when I think about the blood spots in my ears, I wonder if earrings, earrings, or piercings affect me. Lately, I've been forced to wear a mask to prevent Corona19, and I'm wondering if the string stimulates my ears, too, affects these blood points.
