Why does the Sanxingdui civilization, with such a long history, leave no written records?

Sanxingdui, an ancient site located in Sichuan, China, has always been shrouded in mystery. The unearthed bronze divine tree, resembling a towering sacred tree with three layers of branches laden with fruit, mythical birds perched on top, and winding dragons. This divine tree is not only finely crafted but also filled with mysterious symbolic significance. Does it carry the ancient people's awe and imagination of the universe?

Take a look at those bronze masks, with their peculiar appearance, twisted heads, and flowing hair. Experts speculate that these may have been used as base supports for screens by the rulers of Shu. Do these masks reveal some kind of belief or custom prevalent at the time?

And then there are those huge human-faced masks, with bulging eyes, mouths, and ears unbelievably large. Does such a design imply some special significance? Is it a symbol of belief or a manifestation of some mysterious power?

The origin and disappearance of the Sanxingdui culture have always been a mystery. According to expert analysis, the Sanxingdui culture appeared at least 4700 years ago, while the earliest oracle bone inscriptions can only be traced back to around 3500 years ago. The technology used to make these bronze artifacts far exceeds that of contemporaneous Shang and Zhou artifacts. So where did the Sanxingdui culture come from? And how did it disappear?

Some speculate that the Sanxingdui culture may be related to extraterrestrial civilizations. However, this speculation lacks scientific basis and is more a product of people's fear and imagination of the unknown. It is more likely that the Sanxingdui culture was a unique, highly developed civilization that gradually declined and eventually disappeared for some reason.

What is surprising is that no artifacts similar to the style of Sanxingdui have been unearthed anywhere else in the world. The only thing that overlaps with it is China's ancient book "Shan Hai Jing." Some of the artifacts unearthed in Sanxingdui are remarkably similar to the descriptions in the "Shan Hai Jing." Does this mean that there is some deep-seated connection between the two?

The site has been dormant for thousands of years, but when it awakens, it shocks the world. With the continuous deepening of archaeological work, it is believed that more secrets about the Sanxingdui culture will be revealed. This mysterious culture may reveal more unknown aspects of human history to us.
