Is the bedroom facing west or east?

it's good for a building's residential door to face east. As the saying goes, it's smooth when you enter the building. According to Feng Shui, the east is more favorable for the door, so it's better to face east. If the door of the house faces west and it is exposed to the sun in summer, it will be very hot in the house. Most people will decorate it with multiple air conditioners, which will ease the suffering of the exposure to the sun. But it costs a lot.
