Folklore: copper coins to ward off evil spirits in Qianlong era?

Copper coins can ward off evil spirits. Copper coins are rigid and the five elements belong to gold. Copper can absorb the gas field better than gold and silver, so it has the effect of dissolving evil. The outer circle of copper coins, which represents the inner side of heaven and earth, and the year number of Emperor Zhong represents people, has set up "heaven and earth people", thus having the effect of reversing heaven and earth. Of course, copper coins generally refer to copper coins cast in Shunzhi, Kangxi, Yongzheng, Qianlong and Jiaqing periods. At that time, the exquisite circulation of China's national wealth, emperor Zun and emperor's coins took a long time, which at most brought together the essence of "the right place and the right time". There is also the five-element collection from Shunzhi to Jiaqing, which happens to be 180 years, and it is a complete three-yuan nine-luck, so it is extremely powerful to wear the money of these five emperors with red lines! ! !
