For Feng Shui, does every mountain have a Long Mai? Please, 3Q.

No, you can't meet Long Mai, because Long Mai will change as the weather changes. Long Mai is basically divided into nine types. In fact, the ancestors of many people who can watch Feng Shui are grave robbers, and Long Mai is not necessarily in the mountains. Dragons are born when they meet water, and they generate dragon souls. Basically, places with Long Mai have negative protection for future generations.
