The five emperors' money hanging on the door must be real antiques to work. The copper coins of the five emperors Shunzhi, Kangxi, Yongzheng, Qianlong and Jiaqing were all blocked by imperial power. But as for where to hang it and where to bury it, it must be handled by the feng shui master. You'd better persuade yourself not to hang anything. Different positions will lead to different specific practices. Hanging in the wrong place or going to the wrong town is bad luck!
Supplement:
What should be given to your family is the flying blade demon, which is usually solved by burying the five emperors' money in the threshold. (It's best to find a feng shui master)
