In the 1930s, the Sanxingdui site was discovered. Because the excavated cultural relics are too absurd and strange, and they are quite different from the Central Plains bronze civilization at that time, it has caused more than 50 years of controversy among the parents of archaeology in the world. According to the data, all the cultural relics excavated from the Sanxingdui site do not have writing, and there are only 6 strange conformities in total. Sanxingdui is the embodiment of the ancient Shudi Chinese civilization, but all the excavated cultural relics are some very strange shaped objects.

For example, some strange face masks look like ghostly faces, and some are kind of golden tree birds. At that time, some people still thought that these things came from West Asia, but this land belonged to the former Chinese civilization area, so the west Asian saying was pure nonsense. However, so far, there are still 3 mysteries in the Sanxingdui ruins that have not been solved. The Sanxingdui site is more than 4,500 years old, but some of the artifacts unearthed in its sacrificial pits seem to be handicrafts unearthed in modern times.
The carving techniques of these excavated bronzes and jades seem to be methods that can only exist in modern times. At that time, the land of Western Shu was too far away from the Yin merchants of the Central Plains, but its process technology could be compared with the Central Plains. In addition, the Sanxingdui ruins show the high civilization of Shudi in those years, but how did such a prosperous place disappear in history? These are the first mysteries left by Sanxingdui.
The second mystery is that the Sanxingdui urban drainage system is almost the same as today's modernization, and it is reasonable that thousands of years of Shudi should not have such advanced technology. The third mystery: Is the Sanxingdui civilization related to the Yangtze River Basin civilization, or to the Southeast Asian and South Asian civilizations? Many jade artifacts have been excavated at this site, among which the jade bi and jade zhang are very similar to the cultural relics found in the Liangzhu culture of Zhejiang in the Central Plains.
At the same time, the sacrificial jade artifacts at the Sanxingdui site are very consistent with the Zhou Rites. Therefore, there may be a connection between the Sanxingdui civilization and the civilization in the Yangtze River Basin. Sanxingdui also has a lot of ivory, Sichuan is not suitable for elephants to survive, but this place is relatively close to Southeast Asia and South Asia, so Sanxingdui may have exchanges with Southeast Asia and South Asia. Shudi is mountainous, more than 4,000 years ago, the traffic is very inconvenient, how did these elephants come in from foreign countries?
Since there is no written historical record, the civilization at the Sanxingdui site seems to lack strong evidence to prove the speculation of experts. In fact, there are many records in the ancient book "Shan Hai Jing" that are very consistent with Sanxingdui. There are depictions of square Qiang people in the Classic of Mountains and Seas, and similar bronze statues have been unearthed in Sanxingdui. According to the "Classic of Mountains and Seas", it seems that the Yellow Emperor's war worms occurred in the Sanxingdui area. Although there are many myths and legends described in the Classic of Mountains and Seas, the cultural relics of the Sanxingdui site just prove that the records in this ancient book are not imaginary, but are likely to be real history. It is believed that with the passage of time, the 3 mysteries of Sanxingdui will be solved.
