Geographical advantages determined the location of the imperial capital. The Yellow River Basin is the cradle of ancient Chinese culture, Heluo culture is the source of Chinese civilization, and Luoyang is the pearl in this cradle. It is located in the west of Henan Province, between 111.8' and 112.59' east longitude, and 33.35' and 35.05' north latitude. ; The eastern section of the Eurasian Continental Bridge, spanning both banks of the middle reaches of the Yellow River, is known as the "Heartland of Kyushu" "among the rest of the world".
Luoyang has superior geographical conditions. It is located in the transition zone from the southern edge of the warm temperate zone to the northern subtropical zone, with four distinct seasons and a pleasant climate. The annual average temperature is 14.2`C and the rainfall is 546 mm. It borders Zhengzhou to the east, Sanmenxia to the west, Jiaozuo across the Yellow River to the north, and Pingdingshan and Nanyang to the south. It is about 179 kilometers long from east to west and 168 kilometers wide from north to south.
Every place where the imperial capital is located has its unique Feng Shui features. Luoyang is known as the "ancient capital of the Thirteen Dynasties". Since King Cheng of Zhou Dynasty "looked at Santu in the south, Yuebi in the north, the river in Guzhan, and Luoyi in Zhan in Guangdong", kings of all dynasties have listed this land as one of the first choice locations for building their capitals, mainly due to its feng shui shape. Li Sicong of the Ming Dynasty gave a very detailed description in "Kanyu Miscellaneous Records": The Luoyang Dragon Vein originates from Zhongyue Songshan Mountain, passes through the gorge stone to the north, and transforms into a Ganglong. Although the mountain is not high, it is winding and long, rising from Shouyang Mountain. The head is reflected in the distance, ending in Gong County and ending in the Yellow River. The middle part of Songshan Mountain was extracted, and the imperial mausoleum was built. The mountain branches off to Heishiguan, which is the mouth of the water. The center is expanded into a hall, while the four mountains are tightly arched and the front peaks are beautiful. Yi, Luo, and Xianjian meet in front, which is the right boundary water of Long; Choosang, Hongnong, and Haoyang streams are the left boundary water, flowing into the Yellow River and winding behind Beimang. The Luo River is melodious and reaches Gong County where it joins the Yellow River. It can be said to be “one big city”.
Luoyang was the ancient capital of thirteen dynasties, and the central axis of its imperial city determined the planning and layout of this ancient capital. According to the relevant research works of scholar Zhai Zhigao, he believes that "Regarding the feng shui line of the central axis of the capital, "Zhou Li" says: "Only when the king builds a country, the direction of the country is determined, and the position of the people is considered to be the pole." This means that the direction of the capital must be clearly identified. The correct position must be determined , that is, the central axis must be straight. The so-called straightness means that the central axis of the capital should be parallel to the meridian of the location. Throughout the ages, the central axis has been carefully chosen when establishing capitals." The ruins of the five major capital cities in Luoyang (Xia Erlitou, Shangyanshi Shangcheng, Zhou Wangcheng, Han and Wei Luoyang City, and Sui and Tang Dynasty Eastern Capitals) are arranged east and west in the Yihe Luohe Basin: forming the central axis of Luoyang City in the Zhou, Han, Wei and Northern Wei Dynasties, basically It is a natural double-que peak facing the main peak of Wan'an Mountain in the south.
This is largely due to the factors of ancient Feng Shui masters. Mang Mountain is a famous historical mountain. You can look up at the steaming clouds and the rosy clouds, overlook the east flow of Luoyi, rest on the big river, face the young family, hold Taihang in your arms, and cross the Han Valley. It is a treasure land that hides the style of Yan Huang Emperor and absorbs the ancient charm of civilization. The reason why Mang Mountain Feng Shui is good is also The main good thing is that Cuiyun Peak was the place where I made alchemy back then. Taoists call this Cuiyun Peak "Jintai Jade Bureau". A Taiwanese scholar who studied Feng Shui once said: If Mang Mountain is a good mausoleum, then the Qing Palace above the dragon veins will be the "mountain" for this mausoleum. This treasure cave in Luoyang gathers the royal energy, and the Shangqing Palace "zhenshan" suppresses the royal energy. Therefore, Luoyang carries the reputation of "the ancient capital of thirteen dynasties" in Chinese history.
