Why don't urban houses look at Feng Shui, and why do rural houses pay attention to Feng Shui?

Hong Kong and Taiwan have to look at it, and the house can't be sold unless it is repaired in line with Feng Shui. Do you know the mainland developers who care about this, just to sell houses, no matter whether the feng shui is good or not, everyone has paid attention to it in recent years. In the countryside, everyone knows some basic knowledge, because it is handed down from generation to generation. There are no roads in the city.
