Can the photo be hung against the door?

don't face the main door, kitchen door and bathroom door, and if there are other bedroom doors at home, don't face them. The reasons are as follows:

① Facing the main gate, you can see your photos when you go home and open the door, which is unlucky in geomantic omen.

② Right in front of the kitchen door, all the oil during cooking comes through the air circulation, which is easy to get oil stains on the photo sheets, which is also very bad for health.

③ Facing the bathroom door, the bathroom is a place for us to handle personal hygiene, and it is easy to spread the foul air through the air.

④ if you are facing other doors, it's not good, it's just a little revealing.
