Can I hang the key with five emperors' money?

Five emperors' money can be used as a key, but the following points should be noted:

1. The five emperors' money must be genuine, and can be purchased through formal channels or from people who understand the principle of geomantic omen.

2. The key hanging position should be moderate, neither too low nor too high, and it is generally more appropriate to hang it in the trouser pocket of the left hand.

3. It should not be hung on the key for too long, and it can usually be hung for several hours or days to achieve the effect of dissolving the magnetic field.

It should be noted that the above method is only a folk custom and has no scientific basis. In addition, if there are special local customs, we need to respect them.
