After the renovation of my home, the bed was put to sleep with my feet facing the door. What's wrong with this?

It doesn't matter if it's wrong; This is because it is unsightly to forget to open the door or when someone enters the house, because in ancient times, rich families had daughters or servants, and it was unsightly to enter the house and someone slept in bed, so the ancients said it was a ghost.

The second is about the magnetic field (or wind or airflow, gas field), because when the magnetic field comes in from the door, if the feet are outward, it will not be poured from the feet to the head. If it is a bad magnetic field, it will be a nightmare.

In addition, don't sleep with your head out, except for the taboo of stepping out.
