What cultural relics unearthed from the tombs of the Three Kingdoms have been debated by experts for 50 years and become unsolved cases for a hundred years?

Experts found aluminum in the ancient tombs of the early Zhou Dynasty during the Three Kingdoms period. Because aluminum is a product of modern science, and the early Zhou Dynasty was a figure in the Three Kingdoms period, there is a great controversy about aluminum. Some people say it came through, others say it was brought in by grave robbers, but it was later overthrown. After more than 50 years of research by experts, there has been no result and it has become an unsolved case in the century.

The most familiar names of the three kingdoms are probably Zhang Fei, Lu Xun and others. There is also a name called Zhou Chu, which is not very familiar. He was the satrap and general Jianwei of Dongwu in the Western Jin Dynasty. His name has a high popularity in textbooks. His first fame 1 was not because of his military talent, but because of an allusion to eliminate three evils in Early Zhou Dynasty. At that time, at the beginning of the week, I was always bullied in my hometown because of my better birth conditions. Because of this, he became a typical prodigal son in history and was written into the textbooks of primary schools.

He became famous for archaeology for the second time. A middle school in Jiangsu Province found an ancient tomb when it was being renovated. After investigation, it was found that the owner of the tomb was at the beginning of the Zhou Dynasty. Unfortunately, the tomb has been excavated by grave robbers many times. Later, archaeologists found 17 metal bands with hollow patterns in human bones, and later sent them to the chemistry department of the university for composition inspection. The test results surprised the experts because 85% of them were in it.

Aluminum is a difficult metal to extract. 1825, foreign scientists extracted a few milligrams of aluminum from the laboratory for the first time in 1 and it was not until 1886 that large-scale refining began. Aluminum is the product of modern science, but at the beginning of Zhou Dynasty, it was a figure in the Western Jin Dynasty of the Three Kingdoms, so aluminum was found in his tomb. Some people even suspected that it was crossing, and others said that it was because his tomb was dug many times and was later brought in by stimulants. But this statement was later overturned. After research, it doesn't look like it was brought in later. In this way, this matter has been discussed by experts for nearly 50 years and has become an unsolved case of the century, with no conclusion.
