Which is better, five emperors' money or nine emperors' money?

Differentiated from each other, the five emperors' money refers to the copper coins cast during the reign of Shunzhi, Kangxi, Yongzheng, Qianlong and Jiaqing in the Qing Dynasty. These five copper coins strung together will have the power to ward off evil spirits. Nine emperors' money and the number of "nine" belong to "fire" in Feng Shui, which can be used to relieve Muduo. When this combination of copper coins and "eight emperors' coins" are used together, it can achieve the purpose of "eight times purple" and is used to attract peach blossoms and benefit marriage. Another "nine" is the supreme number, which is combined with nine continuous copper coins used by the Qing emperor to form a string, which has a special role in prospering the official transport and helping the authorities.
