First, the daughter country.
We know that the girl country is known from Journey to the West. We always thought it was a virtual country before, but later we found that the daughter country appeared in Old Tang Book. The scientific name of the girl country is "Oriental girl country".
But strangely, later generations did not find any historical traces of the girl country, nor did they find any documents about the girl country, let alone how the girl country disappeared. It can be said that it is a very mysterious change.
That country is different from other feudal societies. The people of the whole country are women, and women's status is supreme. Absolute authority, emperors and ministers are all women, and the reproduction of the next generation does not depend on men at all. This is the ideal country in the hearts of many girls.
Second, the Terracotta Warriors
As one of eight wonders of the world, the Terracotta Warriors really shocked the world.
Not only the images of different colors and shapes used by servants, but also the weapons in their hands are even more surprising.
Among them, Wang Goujian's sword, which was discovered by chance, is fine in workmanship, with a sharp iron as mud and no trace of corrosion.
After testing, the researchers found that a layer of chromium salt compound can prevent the sword from being oxidized. This discovery caused a sensation in the world, and attracted a lot of criticism for the Terracotta Warriors, because this chromium salt oxidation treatment method was invented by Germany and the United States in 1937 and applied for a patent in 1950.
Some people question the academic fraud of Chinese terracotta warriors and horses, but it does exist in ancient buildings, and it is also a fact that some things have not been oxidized. This matter is still unacceptable and has become a mystery. With the development of science and technology, more and more historical sites will be discovered in the future, and this mysterious veil may be unveiled.
