The water facing the mountain is the most basic principle of Feng Shui. Mountain is the skeleton of the earth, and it is also the natural reservoir of people's living resources. Water is the source of all life.
The site selection of ancient settlements in China is mostly located in the meandering ring of rivers, and a few are located outside the meandering ring, which conforms to the principle of geomantic omen. Humans choose a horseshoe-shaped concave land with mountains and water at the back. Such places are often green mountains and green waters, and the whole ecological environment presents a sense of stability and peace.
According to China's geomantic theory, "facing the sun" is a necessary condition to become an auspicious place and house. Feng Shui calls mountains as yang, water as yin, Nanshan as yang, Beishan as yin, north water as yang and south water as yin. Therefore, the terrain should be backed by mountains and waters. The high temperature, abundant sunshine and high terrain are collectively referred to as Yang, while the shady places face the "Yang". From life experience, people realize that "Yin-yang disease is caused by Yin and Yang, while Yangyang's disease is caused by Yin and Yang" (Su Wen, Yin and Yang should be alike). Therefore, feng shui masters must choose "the combination of yin and yang" and look for "the combination of yin and yang, and the wind and rain will surely". Only in these places can "yin and yang be appropriate, and when the wind and rain come, the spring is full and the people benefit."
"Xue Xin Fu" says: "If you want to understand the trend of separation and integration, you must first assess the situation." The "back" here means "yin and yang". "House Classic" advocates that the door stands in the "Yang", and the book divides the east (Yang) into three dimensions: Jiamao B. Guan's geographical indication says: "The way to choose the direction ... take pictures of the shining sun and moon in the sky".
The ideal environment mentioned in Feng Shui should be backed by Zushan, with Qinglong on the left and Baihu Mountain on the right, with broad prospects and mountains in the distance. Water flows out of the mountain and winds around the front; It is best to have multi-level mountains around, that is, besides Qinglong and Baihu, there are mountain guards surrounded by each other, and there are opposite mountains in front of the mountains; It is best to sit north to south; In this way, a good area surrounded by mountains is formed, with negative yin and yang and mountains and water behind it.
