Why the topography of the house should be sunny and not shady

The terrain is divided into yin and yang. The south of the mountain and the north of the water are called Yang; the north of the mountain and the south of the water are called Yin. The ancients lived mostly by the mountains and rivers, and many cities were built on the waterside and mountains. For example, there are many place names in Daiyang, Henan Province with a long history, and it can still be seen that the cities built on the waterside include Luoyang, Puyang, Huaiyang, Biyang, Qinyang, Ruyang, etc. As far as the general condition of the terrain is concerned, the sunny place is the surface, and the shaded place is the inside. The house should generally be on the sunny side, not on the shaded side. The reason is that the sunny side is dry, and the shaded side is generally very humid, which is not conducive to living and health.
