What is a pure yang and pure yin house? Please enlighten me, thank you! !

I don’t dare to be a master. You also know the Eight Diagrams. According to the theory of the Yangzhai Three Essentials School, the door, the master, and the stove. Among them, the main door is all in Qiankan. Genzhen is called Chunyang house. On the contrary, the door, the owner is in Xunli Kundui, which is a pure Yin house. I see your name is a Feng Shui master. To be more specific, when it comes to determining the sitting direction on the compass, you cannot casually judge a house as pure yang or pure yin, be careful!
