Generally, it is best to put 8 coins or 16 coins under the pillow. Because of the 8-way "hair", many users choose to put 8 coins under their pillows, hoping to increase their wealth.
But don't think that the more 8, the better. Too much is not a good thing. Four eights is a disaster. The feng shui meaning of putting six is also very good, which means good luck, so putting eight coins or six coins is a more appropriate number.
The origin of the custom of putting coins under pillows
In ancient times, money was regarded as a "blessing". As a currency, money often circulates in the market. Coins will be handed down by countless people. It is said that this will contaminate the spirit of a hundred schools of thought, and then string these coins and copper coins and hang them on your body, which can play a role in expelling drugs and evil spirits.
Moreover, money is a spiritual thing that can affect people's fortune. It is said that an old hen who doesn't lay eggs will lay eggs when she sees it. This is called "eggs attract eggs". Therefore, the elderly also think that putting money under the pillow, just like an old hen laying eggs, can be Qian Shengqian. So there is a saying that you can make a fortune by putting coins under your pillow.
