The westernmost part, commonly known as Xifangshan or Xizhuang, takes second place in lighting, but the sunshine in the west is short in winter, easy to dissipate heat when it is not warm, and hot in summer!
The central part has the worst lighting, but it is warmer than the western part in winter and cooler in summer!
If there are windows on the easternmost gable in Orient Mountain, it is suggested that it be Dongfangshan. After all, it is not the roof, and the possibility of side leakage is small!
If Fangshan has no windows and the middle room is transparent from north to south, it is recommended to be in the middle!
