Feng Shui Long Mai drops rapidly and sinks into the cave.

Feng Shui Long Mai quickly descended into the cave. In Feng Shui, Long Mai won't sink into the cave until he has experienced, undressed and changed clothes, mastered his breath and opened an account across the gorge. Long Mai's geomantic function is that it can be used to obtain exuberant luck and make it flow like a dragon. This answer is for reference only. Don't be blindly superstitious.
