Three defeats and seven defeats of Feng Shui

In this national condition, it is difficult to find a good cave, and finding it may not be something you can find. In fact, it is even harder to find a cave that failed in failure. I looked for it once before, but it was entrusted by people. After I found out, I ignored it, but it was not a big defeat. It's just a bare mountain. All the birds and basalt are smelly rivers, while the dragon and tiger are rugged and rotten mountains, and the soil under the cave is dark and wet.
