The biggest difficulty of Feng Shui is that the theory is easy to understand. There are too many kinds of actual geographical situations to distinguish, so the same thing will be completely different when used concretely. Therefore, the old saying goes, "I will wait for the king and you will give it to the beggar." That's what it means. In particularly advanced geomantic omen, it is even more different to cooperate with time and the owner's situation to achieve the effect.
