There is a pond a few meters behind the house, facing south, with roads in front and houses on both sides. Is feng shui good?

There is no problem with feng shui in such a house. Don't worry. Everything's fine. In fact, when it comes to feng shui, there is no big problem. Besides, the so-called geomantic omen is all folk customs in the past, some of which have no scientific basis and some convincing reasons. So in real life, we know that it is scientific to build the house at a suitable height, which will not make the house wet or sunrise, and the terrain is not very low.
