Working in a jewelry store will grind cocoons on your feet. Working in a jewelry store requires standing or walking for a long time, which will cause pressure and friction on the feet, thus forming cocoons. Cocoons are formed because of the skin's self-protection response to repeated pressure and friction. When working in a jewelry store, it is recommended to choose suitable shoes, rest and relax your feet at work, and reduce the pressure and friction of your feet. So working in a jewelry store will grind your feet.
