In ancient China, people regarded the east as the direction of sunrise, and thought that the sun was the spirit gathered in the east, which could be related to the fact that everything should move towards the sun. According to this geomantic principle, when arranging the ancient stage, the builder will "sit west facing east". This arrangement not only appeared in ancient buildings in China, but also was adopted in many modern buildings. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
