According to media reports in China, experts and scholars have been arguing over the "seven mysteries" in particular, but all of them have become unsolved cases because there is no conclusive evidence.
The first mystery, where did Sanxingdui culture come from?
At present, some people think that the source of this problem is related to the Neolithic culture in the upper reaches of Minjiang River, the prehistoric culture in eastern Sichuan and western Hubei, and the Longshan culture in Shandong, that is, people think that Sanxingdui culture is the product of the integration of indigenous culture and foreign culture and the result of the interaction of various cultures. But where did it come from?
The second mystery, what race are the residents of Sanxingdui site?
At present, there are different views on, Pu, Ba, Dongyi and Yue. Most scholars believe that the sarcophagus burial culture in the upper reaches of Minjiang River is closely related to Sanxingdui, and its main residents may be the Bianqiang family from northwest Sichuan and the upper reaches of Minjiang River.
Because the portraits and masks unearthed in Sanxingdui are very strange, some people speculate that they are "alien civilization" and even have a sensational saying: "alien civilization."
However, Chen Dean, an expert from Sichuan Institute of Cultural Relics and Archaeology and the stationmaster of Sanxingdui Site Protection Station, said that the unearthed cultural relics were not realistic, and those heads and masks might be the "gods" in people's minds at that time. It was "not very convincing" to judge the race at that time with those grotesque shapes.
The third mystery, what is the political nature and religious form of Sanxingdui ancient Shu State?
Is Sanxingdui Ancient Shu a tribal military alliance attached to the Central Plains Dynasty, or a relatively independent early country that established a unified dynasty? Is its religious form nature worship, ancestor worship or deity worship? Or both? None of these questions have been answered yet.
The fourth mystery, how did the superb bronze smelting technology and bronze culture of Sanxingdui Bronze Group come into being? Is it developed by Sichuan alone, or is it the product of the influence of Central Plains culture, Jingchu culture or foreign cultures such as West Asia and Southeast Asia?
The fifth mystery, why did Sanxingdui ancient Shu kingdom come into being, how long did it last, and why did it suddenly die out?
The prosperity of ancient Shu lasted 1500 years, and then suddenly disappeared. When history was reconnected, a mysterious gap of more than 2000 years appeared.
At present, there are flood theories, war theories and migration theories, but there are no good reasons for how the ancient Shu kingdom perished.
The sixth mystery, when and what nature were the two pits where thousands of cultural relics were unearthed?
At present, there are different opinions about the age, such as Shang Dynasty, late Shang Dynasty, early Zhou Dynasty, Western Zhou Dynasty, Spring and Autumn Period and Warring States Period.
The seventh mystery, the great mystery of post-Shu culture, is "Bashu Yu Tu".
Is the symbol on the treasure unearthed from Sanxingdui, the earliest golden staff in the world, a character? Is it a family emblem? Is this a painting? Or some kind of religious symbol? It can be said that if the mystery of "Bashu Yu Tu" is solved, it will greatly promote the mystery of Sanxingdui.
According to the media yesterday, the archaeological team was quoted as saying that the excavation work still needs "120 years". Archaeologists believe that the eternal mystery of Sanxingdui will be gradually solved with the comprehensive study of the mineral source and casting technology of bronzes.
