Why do the main hall doors all face south?

1. Our country is located in the northern hemisphere. Houses facing north and south face the sun better. Think about it, houses facing south and north will hardly see sunlight all year round. Houses facing east and west will either not see sunlight for half the day, or they will get hot in the afternoon. So in terms of comfort, of course everyone likes to live in the north house. The main house is the most important house of the family and is used by the most "respectable" person in the family. Of course, the main house faces north and south.

2. Since ancient times, the Chinese nation has paid great attention to Feng Shui. In fact, Feng Shui means to hope for "smooth wind and smooth flow" and "comfort and convenience". In fact, it is similar to the first one. The meaning is the same.

3. Since ancient times, all dynasties in China have had palaces (main halls) and the Jinluan Hall where the emperor sat facing south. Of course the people should learn from the emperor and naturally let the main hall sit. North faces south.
