The money of the five emperors can be worn with you. It can be hung on gates and town houses to ward off evil spirits, prevent villains from making money, and eliminate the suffocation from door to door and door to stairs. It can be hung on cars to ensure driving safety, and it can be placed in cashier's safe to highlight the effect of making money.
When hanging, you can hang it on the door frame or the wall next to the door with a hook. Don't nail it. Generally, it is not necessary to choose auspicious time, and the Chinese characters are facing outwards (it says that Kangxi and Bao Tong face outwards). There are other questions that can be consulted in the Authentic Pavilion.
