Erlangdong, Tianjun County, Ximeng and Tibetan Autonomous Prefecture, Qinghai Province, China, is the famous Western Wangmu Stone Room. Erlangdong is the site of the late Western Wangmu Kingdom, while the early Western Wangmu Stone Room is in Zongjiagou under the Sun Moon Mountain in Wuyuan County. To illustrate this problem, we must first examine it from the historical environment of the Western Kingdom. In the ancient times, the Western Kingdom had a very close relationship with the Central Plains, such as "when the Yellow Emperor, the Western Kingdom rode the white deer to offer the white ring". "Feng Dushan, the West saw the Wangmu." "From heaven to earth, the West King's mother gave white jade", etc., because the facts and myths are difficult to clearly judge, let alone say. If from the Yin Xu Bu Ci repeatedly out of the "Western Mother", to the "Bamboo Book Chronicles", "History Books", "Han Books" and other letter history, clearly record the history of the Western Wang mother country, this has been at least 3,000 years. In such a long historical period, the Western Wangmu only lived in a stone room, that is, Erlangdong in Tianjun County, I am afraid that Erlangdong has been sitting through it long ago, right? The Western Wangmu is a nomadic and agrarian monarchy, and the ruling area is very large. As usual, all the nomadic kings of the kingdoms are to rotate around the Quartet and govern the country, and the mother of the Western King is not an exception, which is also the national needs of her rule. Secondly, the Western Kingdom is a large country on the Qinghai-Tibet Plateau, which is dominated by the Yi people. During its heyday, the jurisdictions include today's Qinghai, Gansu, northwest Sichuan to the upper reaches of the Shaanxi Lihe River. The central area of economic and political science is the "three rivers" pointed out by historians. That is, the upper reaches of the Yellow River, the Lishui River, and the Datong River Basin. The Li people live for the longest time in the above areas. The representative of the Li culture, that is, the Kayo culture, in my opinion, the culture of the mother country of the Western king, is concentrated in the tombs of Datong, Xining, Lizhong, Xunhua and other places. It can be used as evidence of the area of the center of the great times. The top culture unearthed at Wuyuan Dahuakayo Tomb proves that the political center of the Western Kingdom is in Wuyuan, and the Zongjiagou stone caves, which are only more than ten kilometers away from Dahua, are the Western King Mother Stone Rooms of this period. The Western Wangmu due to the vast area and strong national strength, so the Central Plains Dynasty attaches great importance to the relationship with this western power, and constantly has cultural, political and economic exchanges. For example, Zhou Mu Wang ran for thousands of miles and came to meet the Western Wangmu. And "leap and forget to return" is not the only thing people are happy about today is the beauty of the Western Wangmu. Zhou Mu Wang "not happy Chenxu", and the harem is beautiful like a cloud. So it is not so. He is to attack the dog's fin to remove the threat of the dog fin to the Zhou Dynasty, and come to the Western Wangmu country to engage in a united war. "Le and forget" is because he is confused by the beautiful, mysterious, vast natural landscape of the Qinghai-Tibet Plateau and the richness of everything in Kunlun Mountain. In the Spring and Autumn Warring States era, the relationship between the Central Plains Dynasty and the mother country of the Western Kings has changed significantly. First, the rise of Qin, attacking everywhere, opening up territory, Qin Xian public soldiers Linyi head, the people moved west, to the beginning of the West Han Dynasty, Huo went to the disease to seek Hexi, Zhao Chongguo River Tuntian, the forces of the people gradually moved to the surrounding three rivers and the sun and moon Shanxi, as big as this period, The political center of the Yi people moved to Qinghai Lake area, and then there was Erlang Cave, the western king mother stone room.
