It should be noted that it is best to use ancient coins to ward off evil spirits, that is, real ancient copper coins, and the imitation effect is not good. You need to wear red rope or five-color thread (red, green, black, white and yellow, which is consistent with the five elements). There is no need to open the light, because the use of copper coins is not religious.
Most copper coins are worn around the neck or waist. Of course, it is also possible to make anklets and bracelets. The direction is convenient for individuals, and men can be left and women can be right. Don't be too rigid.
