It is good for the old man to live in that bedroom in feng shui.

According to common sense, the son and daughter-in-law sleep in the east, because the old man gave up the room with the best lighting.

If you are filial enough, make way for the east, because the west is sunny and sultry in the evening. Young people often turn on the air conditioner, but old people are reluctant to turn it on.

The space behind is relatively small, leaving it for the third generation who live alone.
