Can you put something on the door frame of Feng Shui knowledge?

Yes Depends on what you put. (This is quite professional in ancient times. I found that many ancient houses are like this.

There are magnifying boats inside and outside the ship. Some put silver dollars and gold ingots, and some put five emperors' money.

There were craftsmen who made doors in ancient times, and metaphysics tended to be auspicious. There are also evil laws.

Feng shui masters also have methods to make money and treasure, and of course they also have methods to ward off evil spirits.
