Talking about dragons in haunted houses. Cave, sand, water, direction, the old saying goes: there is no Jedi, only direction. No matter where you start, the direction should be based on the terrain, not where you say. In fact, it doesn't matter what it is, as long as it is suitable for the five decisions, it is better. Of course, feng shui is ridiculously big. Don't touch it as long as it is good now, or the consequences will be very serious.
