2. The principle of "left green dragon and right white tiger, before rosefinch and after Xuanwu" is the first choice for land selection. This is feng shui's summary of the terrain around the cemetery. In fact, it is surrounded by mountains and has a spacious basin in the middle. The "cave" of Feng Shui theory is in this basin. The water source of Simian Mountain Peak is called the mountain peak, which is good or bad, and it also reflects the geomantic view of ancient funeral.
3. The principle of bending is straight and smooth curve. The road has to be curved, and the mountains and rivers have to be curved, which means winding, and the winding path is a good pattern.
4. The principle of opening Tang Ming is to climb the mountain to see Shuikou and enter the cave to see Tang Ming. Mingtang is open, full of vitality and promising. On the contrary, cemeteries should not be located in narrow and limited valleys.
5. The truth of returning to the original is that the geomantic omen of Yin house is just the opposite of that of Yang house. Urban people advocate the unity of people, people and computers, and the environment and efficiency come first. The cemetery emphasizes nature first and the harmony between man and nature.
6. The principle of headwind water supply The cemetery also pays attention to "headwind water supply". The upwind direction and water supply direction of Beijing are northwest, so the Ming Tombs are located in Changping District, northwest of Beijing. The northwest is determined according to the central axis of Beijing. This central axis starts from the Drum Tower in the north, passes through the Palace Museum, reaches the south gate in front, and ends at Yongdingmen in the south. The center is the Forbidden City, also known as the Forbidden City.
