How about sitting at the back of the house facing southeast and opening the northwest backyard?

But the specific feng shui influence depends on the specific layout and surrounding environment of the house, as well as the exact position and orientation of the door. These factors are difficult to describe in detail in the question, so it is impossible to provide specific feng shui analysis.

It is recommended to consult a professional feng shui master or architect for more accurate advice. They can provide you with targeted suggestions based on detailed on-site investigation and planning.
