What's under the threshold?

This is a custom handed down by our ancestors. Copper coin was the most basic coin in the past. After countless people's hands, the implication is that there is a lot of yang. Putting it at the gate can play the role of wind and water. Don't bring all the bad things outside home, keep them out, just like people can cross the brazier when they are unhappy. This is just a common way to ward off evil spirits every day, and it also has the meaning of making money into treasure.

If there is no copper coin, you can put coins. If your family is a cadre, you can put seven coins under the door. If you are in business, you can put eight coins under it. Then you can use coins to make it "safe to go in and out". You can buy two pieces of cinnabar from the drugstore, spread it under it, and put a peach branch facing south under it. All these will do, as long as you can.

The most common copper coins are five emperors' coins and gossip coins. Five emperors' money refers to the copper coins of the five founding emperors. Wrap it in red cloth and put it in the four corners under the threshold. The 8-hexagram copper coin version is easier to understand, that is, put 8 copper coins in 8 positions at the bottom of the door stone. These eight positions refer to eight directions in the eight hexagrams. In addition, these two installation methods also pay attention to time and location. Just choose a good day. Moreover, the position of the stone should correspond to the auspicious position such as the nearby fortune.
