When I was in college, our school was next to Sanxingdui, and I volunteered there for 2 years, and I came to talk about my opinion.
In fact, there is nothing to hide, but Sanxingdui has always been a mystery, so far can not be cracked, because the entire Sanxingdui site excavated cultural relics, only 6 symbols, these 6 symbols or modern people can not understand what the meaning of the kind, the truth of Sanxingdui is what it is, must rely on scientific testing, text data to support, but now there are only 6 symbols, plus the history books of the same period of that era have very few records of the ancient Shu Kingdom, so it is impossible to interpret.
What does the truth refer to here? In fact, it is mainly the existence of several major mysteries in Sanxingdui.
Mystery one, how did Sanxingdui disappear? Among the cultural relics excavated from the Sanxingdui site, there are a large number of bronzes, pottery, jade, and some ivory, of which the manufacturing process of bronze has been completely comparable to the civilization of the central plains in the same period, and the carving technology and cutting technology of jade belong to advanced technology in that era.
Secondly, the area of the entire Sanxingdui site is very large, equivalent to the level of the capital of the Central Plains civilization period in the same period, the site is an ancient city of the Shang and Zhou Dynasties, and the city's architectural planning, drainage, and functional division are relatively complete.
So the question is, Sanxingdui civilization has developed to this height, the manufacturing process is not lost in the Central Plains, the urban development is not lost in the Central Plains, such a large ancient civilization, why did it disappear? Why didn't you say it was gone? How come there is no record of it at all? Just disappeared into the long river of history out of thin air, what is the reason for it?
however...... There is no answer... Because there is no record, archaeological excavations and scientific analysis have not found the reason.
Doubt two, whether Sanxingdui has exchanges with the Central Plains civilization and other civilizations in the Yangtze River Basin? Among the cultural relics unearthed in Sanxingdui, many of the jade objects are highly similar to the Central Plains and other contemporary civilizations in the Yangtze River Basin, such as the Jade Bi, Yu Huang, and YuZhang of Sanxingdui, which in the Central Plains civilization, according to the Zhou Li, are recorded to be made of jade as six instruments, to pay homage to the four sides of heaven and earth, to the cangbi to the heavens, to Huang Zhen to salute the land, to qinggui to worship the east... To put it simply, this means that jade was used to sacrifice heaven and earth at that time, and these jade bi, jade huang, yuzhang, etc. unearthed in Sanxingdui are very similar to those unearthed in the Central Plains and the Liangzhu culture in Zhejiang, all of which are of this shape, then their cultural connotations should be the same.

So the question is, was the Sanxingdui culture cultural exchange with other civilizations such as the Central Plains culture and the Liangzhu culture in the Yangtze River Basin at that time? If there is, then the problem comes again, since the ancient Shu is more rugged, the mountains and rivers are steep, even in and out of the Qin and Han Dynasties, you have to take the boardwalk, the boardwalk is on the cliff.
The era of Sanxingdui's existence is still the Xia Shang Zhou period, the means of transportation and road conditions at that time, it is almost impossible to go out of Shudi, so how do they communicate? however.... Similarly, in the absence of written information, it is impossible to rely solely on excavated artifacts.
Doubt three, is there any exchange between Sanxingdui and Southeast Asia and South Asia? Sanxingdui unearthed some ivory, as well as the Jinsha site in Chengdu is generally believed to be the cultural inheritance and development of Sanxingdui, but also unearthed a large number of ivory, but at that time, Sichuan was located inland, the climatic conditions were not suitable for elephants to survive, and there were no elephants in Sichuan at that time, these ivory is believed to come from Southeast Asia, South Asia.
Secondly, there are many types of jade in Sanxingdui that are not native to Sichuan, and many jade materials come from Yunnan, Xinjiang, and some from Southeast Asia.
Then the question arises again, did Sanxingdui have exchanges with Southeast Asia and South Asia at that time, Sichuan is so far away from there, mountains and rivers are blocked, why did you go? The answer is no! Because there is no text, the ghost knows where to go, and there is no way to find any transportation or the like.
There are many other mysteries, all of which cannot be deciphered due to the lack of written materials, and the excavated artifacts can at best prove its age, what it was used for, but... A lot of things can't be guessed right.
