In fact, gold itself cannot ward off evil spirits, but it will inevitably ward off evil spirits after becoming an auspicious thing, and the higher the purity of gold, the better the effect of ward off evil spirits. For example, in the dazzling array of gold ornaments, Zhongtianzhu is highly respected by people. A red rope passing through the golden ball means that luck has changed. In addition, there are the Golden Brave, the Golden Buddha and the Golden Zodiac. It is said to have the effect of exorcism.
The statement that gold can ward off evil spirits has not been strongly confirmed, but it is also people's expectation for gold. Not only gold, but also gold, silver and jewelry were thought by the ancients to ward off evil spirits, so these sayings of ward off evil spirits have continued to this day.
There is also a legend of silver to ward off evil spirits. Because silver is one of the seven treasures of Buddhism, there has been a custom of letting children wear silver ornaments since ancient times, which not only helps to eliminate fetal poison in the body but also plays a role in ward off evil spirits. Silver products can generate a magnetic field in a certain range, release a large number of silver ions, stimulate energy, and have a health care effect on human body.
