What effect does the road in front of the house have on Feng Shui?

There is a saying in the countryside: "there is a cross road in front of the door, and children and grandchildren enjoy wealth." Is there any scientific truth in this sentence? This sentence means that if there is a horizontal road in front of a rural house, then the family will be rich and blessed behind, so why is there such a statement?

As far as feng shui is concerned, good feng shui should be based on the photos before and after, and there should be water or roads in front of the door. China paid attention to geomantic omen in ancient times. They thought that only mobility could bring wealth, so the road in front of the house could bring wealth into the door continuously. More importantly, it was more convenient to park at the door.

Then why is it horizontal and not vertical? From the perspective of geomantic omen, the ancients thought that there was a vertical road at the door, which was a leak in geomantic omen. Every time they open the door, their wealth runs out, which is very bad. Moreover, the countryside thinks that there are some unclean things among the people. If they are facing their home, these unclean things will run along the way home.
