The magnificent "Sanxingdui" site is no stranger to everyone, as the "source of Yangtze River civilization", it is hailed as one of the greatest archaeological discoveries of mankind in the twentieth century. Judging from the excavated cultural relics, the degree of civilization at that time was already very high, such as advanced smelting technology and exquisite cultural relics. But how can a large number of ivory and sea shells appear in closed territories? There are a lot of questions that we can't understand.
The Sanxingdui civilization seems to have little connection with the Central Plains civilization, and it is also very different from the civilizations in other parts of the world. Some archaeologists even say, "I don't dare to delve any further", so why is this? This issue of three pounds will discuss the reasons for this with you, and if there are deficiencies, please criticize and correct in the comment area.
Many of the bronzes unearthed from Sanxingdui have undergone carbon testing, and the test results are that these bronzes do not contain zinc at all, which means that they are pure copper. We know that the solubility of copper is 1084 degrees Celsius, so more than 3,000 years ago, what methods did the ancients use to raise the temperature to more than 1,000 degrees Celsius and refine copper? Moreover, no copper remains have been found near the Sanxingdui site. Through this we can imagine that 3,000 years ago, the ancients were able to extract copper without zinc, which is really incredible. We can also guess whether this technology is a foreign civilization? Why has this technology disappeared in the long river of history? Therefore, there will be experts who say that they dare not study the "Three Star Pile" in depth.
In addition, the "Sanxingdui" culture may affect the source of our Chinese civilization, and the excavated cultural relics are somewhat similar to foreign countries, so many archaeologists are very embarrassed, neither can overturn the cultural identity of thousands of years, nor can they completely deny the mysteries reflected in Sanxingdui, so they can only temporarily suspend the study. That's why archaeologists don't dare to delve into it.
However, our nation has a long history, and many historical facts can still prove the existence of Chinese civilization, and it is not surprising that some special branches have appeared in such a historical background.
