Residential feng shui: What does "water in front of the door" mean?

Hello, I'm a professional Mr. Feng Shui. The so-called "water in front of the door" refers to the front of the porch. In fact, the quality of the water in front of the door mainly depends on the direction of the water flow and the shape of the waterway. The so-called landscape surrounded by feelings can be simply understood as bow bending water and anti-bow bending water.
