Ceng Shiqiang's three-currency divination method

According to the positive and negative sides of the copper coin after being thrown out.

Use three coins to predict bad luck. If the coin is thrown out and removed, it is the positive side, representing the number 9 and the sky, but it represents the negative side, the ground and the number 6.

The implication of "Three Copper Coins" refers to san huang coins issued in Qianlong, Jiaqing and Daoguang periods in Qing Dynasty.
