What is the "rising tile potential" in Feng Shui?

The so-called Tiwa potential refers to the low-lying place in the middle of Xuanwu Mountain behind the cave, such as the upturned shape of roof tiles, hence the name "Tiwa". The trend of rising tiles makes the screen behind the hole empty, but there is no ghost music. Evil winds blow holes, and anger cannot be gathered. It is a place to rest and die, and it is a place with a back against tiles, which is mostly unlucky. Xie Heqing's "Bao Jing" said: "The back is empty, and the defeat falls from the sky."

However, the giant gate star peak (Tiancaixing) has the potential to lift tiles, making its star square and flat, with a slightly concave top, which is an image in the warehouse and auspicious. However, the giant door leans against the tile, and the mountain of ghost music must be intertwined and guarded by all beings behind the cave. Miao Xiyong said in the article "Strange Cave of Buried Sutra Wings": "There are Tiwa people in the cave. The law says: two gold bears one water, and the point is cut in softness. Most of the fortune stars in heaven are backward, and they are happy to have milk and ghosts. "
