Has anyone noticed whether the imperial palace emperor's bed is north-south or east-west?

It's usually north and south. In ancient times, the emperor was very particular about this. Take the palace as an example. There is no even number in the room, only odd number. The emperor's bedroom is also nine. Because odd numbers are used by the living. Even numbers are for the dead. 9 is the maximum value. The south is a fertile land. For our country, we all sit facing south. It means mastering the world. Which emperor doesn't want to keep his position. So in the room, it should also be the head facing north and the feet facing south. Other people's homes are generally not so particular. And every emperor will be exposed to some feng shui skills more or less when he goes to school.
