At first, this "geomantic theory" was only used for the location selection of houses, temples and other human activities. But under the traditional theory of "Yin and Yang", when people die, they go to the underworld and live in another world. Therefore, the location of tombs can't be sloppy. Up to now, when people choose a cemetery for their deceased relatives, they still have to talk about Feng Shui. The location of the Mausoleum is directly related to the rise and fall of the country and the nation, which is particularly valued, because there are not a few Mr. Feng Shui who were killed by the emperor by mistake. But why can't the Mausoleum with such a site stop the demise of the empire and the replacement of dynasties? Speaking of the geomantic omen of imperial tombs, the Ming and Qing emperors showed the most obvious performance in the location of tombs. It is said that the mausoleum of the Qing Dynasty is said to be a treasure trove of geomantic omen personally selected by the emperor shunzhi. According to the expert analysis of Peking University World Heritage Research Center, this place is really an excellent place for geomantic omen. Its basis is that the whole mausoleum area is bounded by Changrui Mountain, which is called "Houlong" in the north and is the source of Long Mai. The mausoleum area is backed by Changrui Mountain, and Yingfei Mountain on the east side is Qinglong; Huanghuashan in the west is a white tiger; In the south, Jinxing Mountain, which looks like a bell, is Chaoshan; The shadow wall mountain in the distance is the case mountain; The Malan River and the West River are winding and surrounded by all beings. It should be said that the Qing Dongling is a water pattern of "mountains surrounded by water, negative yin holding yang". Surrounding the castle peak, it has formed a trend of guarding, hugging and bowing, which is really a land of feng shui. According to the mausoleum building materials left in those years, combined with the traditional "split-phase" geomantic theory, the central axis of the mausoleum building is determined. Xiaoling Mausoleum, the main mausoleum of Dongling, and Jinxing Mountain in the south constitute the architectural axis of the whole mausoleum. The mountains and rivers of Fiona Fang in the whole mausoleum area are controlled by the mountains connected with Jinxing Mountain and Changrui Mountain. This axis is constantly enriched and strengthened under the organic configuration of many mausoleums in the mausoleum area. On the level of spatial sequence, mountains and rivers are in orderly contrast and contrast everywhere, showing a cosmic picture of "harmony between man and nature". The site selection and construction of imperial empresses' tombs in Qing Dynasty are all like this, and the relationship between dragon, sand, cave, water, hall, recent example and distant dynasty has been taken into account. It is expected that Longshan will be reset behind him, the screen will be opened, and the mausoleum will be round and round, avoiding the cold wind in winter. Left and right sand protection, arch enclosing, diversion, wind hiding and scenery gathering. There seem to be several recent cases, and the distant dynasty seems to be a minister, so that the buildings are far from each other and echo each other from afar. When the conditions of natural mountains and rivers are not perfect, they should be repaired, supplemented, filled and dug manually, and the nature and humanity should be organically combined to create an ideal "artificial" geomantic place. The concept of "harmony between man and nature" in the site selection and planning of imperial tombs in the Qing Dynasty was inherited from the Ming Dynasty, and its initiator was the founding emperor Zhu Yuanzhang. In the capital of China, the walls of Nanjing are irregular. If you have been to the best preserved and longest capital city wall in the world, you will find that the city wall is built on the mountain and has beautiful scenery. If the traditional "central axis" theory is square, there will be no "beautiful scenery of Jinling 48" like "Jing Hua Yuan". When Zhu Yuanzhang chose the mausoleum site for himself, he also pursued the harmonious unity between the mausoleum and nature, "following the rules of etiquette and combining the shape of mountains and rivers." Zhu Yuanzhang, the founding emperor of the Ming Dynasty, was the same as the emperors of all previous dynasties, who preferred sons to daughters and respected their ancestors. The difference is that Zhu Yuanzhang is more superstitious and pays attention to the location of the mausoleum to the point of harshness, in order to have a good feng shui environment and bless Zhu's descendants. Some experts believe that the imperial mausoleum system in the history of China was only completed in the Ming Dynasty, which makes sense. The Ming emperors' tombs are distributed in four places, namely, Xuyi "Zuling" buried by Zhu Yuanzhang's grandparents, Fengyang "Huangling" buried by Zhu Yuanzhang's parents, Nanjing "Xiaoling" buried by Zhu Yuanzhang and the Ming Tombs in Beijing. These tombs are all "feng shui treasures". Many experts have studied the "Feng Shui" of ancient imperial tombs in China, and there are many books and papers in this field. When the Ming Tombs declared the world historical and cultural heritage, a report entitled "Interpretation of the World Cultural Heritage of the Ming Tombs" interpreted Xiaoling's "Feng Shui". Zhongshan Scenic Area, which now covers an area of more than 30 square kilometers, is almost the entire area of the Ming Tombs. In this huge area of the mausoleum, the designers regard the whole Zhongshan Mountain and part of the water surface as an important "Feng Shui" landscape, and incorporate it into the architectural planning and design of Xiaoling Mausoleum, thus realizing the architectural tradition and cultural concept of "the mountain is the mausoleum" and "the harmony between man and nature" in China Mausoleum. Zhongshan was called "Longshan" in ancient times. As early as the last years of Jiangdong, it was regarded as "Dragon Pan" by politicians such as Zhuge Liang and Sun Quan. As the founding king of Ming Dynasty, Zhu Yuanzhang would not let go of this treasure, and would naturally choose Jinling "Long Mai" as his burial place.
