This is ancient geomantic omen, with hugs on both sides, indicating that there is a green dragon on the left and a white tiger on the right, surrounded by mountains. A good mountain, surrounded from left to right, is affectionate and can gather gas. Back means the position of the basalt behind.
If there is no mountain in front, that is, there is no building or mountain as a buffer at a proper distance in front, it is too empty and not a good phenomenon. From the requirements of topography, it also reflects the golden mean of China's cultural philosophy, and it is a better arrangement to be prudent and conservative in everything.

The most prominent manifestation of the popularity of geomantic omen in Tang and Song Dynasties is the popularity of burial books and the wide use of compasses. With the birth of Qingnan Gaoyu, Feng Shui became an independent theory, forming a certain system and source. This was determined by the historical environment and scientific development at that time.
From the end of Sui Dynasty to the Tang Dynasty, the enthusiasm of geography to investigate mountains and rivers was high, which promoted the application of Feng Shui theory in the exploration of mountains and rivers. In 7 10, a group of eminent monks in the Tang dynasty put forward the narrative of magnetic declination. Master Li and his party were respected as masters of Feng Shui by later generations.
In addition, Buddhism and Taoism prevailed in the Tang Dynasty, permeated with Feng Shui, especially Taoism's "Qi" theory, as well as Yijing, Taiji, Yin and Yang, Bagua and other theories, which became the theoretical core of Feng Shui in the later period.
