Is it unlucky to wear copper coins? Please tell me what you know.

It is very lucky to bring copper coins, especially to wear dry money. From the perspective of Zhouyi's Eight Diagrams, Gan Long Bao Tong is a strong penis. You can go and see which ones don't use Gan Long Bao Tong. This is because during the Qianlong period, China's feudal economy reached its peak, with a large population and unprecedented prosperity in production and life. The brass used for casting copper coins is pure copper, and the casting process reaches its peak. Copper bar is a precious metal after gold and silver. There is a saying in metaphysics that the higher the purity of precious metals or the higher the fineness of precious metal vessels, the more "positive" (meaning that all evils do not invade) and the more spiritual. As you said, the situation is normal. First, copper coins may turn black. Those black coins are copper oxide, which is harmful to the human nervous system. When you wear them on your body, some harmful substances will inevitably invade your skin and disturb your nervous system. Just polish it with fine sandpaper, and then it will be Huang Cancan's. The more I watch it, the more I like it. Second, you use black rope first, and use black rope to wear copper coins. This is the ancient practice of putting money into the mouth of the dead, so it is unlucky. Thirdly, I suggest you buy two more pieces to form three pieces of Gan Long Bao Tong, and wear them on your body.
