Why did the Feng Shui master ask the door to tilt?

That is probably an evil teacher. After the sitting direction and tuyere position of the house are determined, no matter what direction the door is changed, the position of the air inlet remains unchanged, that is to say, the position of the air outlet and the air inlet (tuyere or door) remains unchanged, which determines the good or bad luck of the house.

The logic of the door slanting dress is that the direction of the incoming air has changed. But their positions have not changed relative to the poles. Good luck or bad luck has not changed.

The book of Feng Shui is devoted to the problem of doors.
