How about a house that is 30-40 degrees south to west?

Okay. Found out according to Qizhuang.com query.

1. The lighting is better, provided there are no obstacles in front.

2. The advantage of south-west is that the main direction faces south, making living very comfortable.

3. Taking into account wind direction and ventilation factors, it is normal for residential buildings to be designed at 30 degrees south to east and west.
