Excuse me, what is the center of the rockery pool facing northwest in Feng Shui?

The northwest direction is the natural northwest direction reflected by the compass centered on the house.

If the land is wide, it may be harmless to build a rockery to grow flowers and plants; But there is no special purpose pool, so it is best not to repair it. "The pond in front of the house is connected with the pond behind the house, and the boy Lang born to die" is not groundless, but there are obvious security risks.
