Many unearthed cultural relics are exquisite in craftsmanship, and their principles cannot be explained so far. What advanced wisdom did the ancients have?

Zhao Zhouqiao, the Mausoleum of the First Qin Emperor and the Great Wall of Wan Li are the crystallization of China's ancient wisdom, and they have their own styles and characteristics. I have to say that the wisdom of the ancients in our country is infinite, and many things invented are very advanced and distinctive. For example, Gou Jian's sword, the transparent mirror of the Western Han Dynasty and the bronze plate are all wonderful, and the principle is quite puzzling.

Let's talk about this sword of Gou Jian, the King of Yue, which belongs to the Spring and Autumn Period and the Warring States Period and is famous at home and abroad. He is particularly interesting. He was buried in the wet ground for more than 2000 years, but there was no trace of rust when he was unearthed, which puzzled many people. What is even more surprising is that there are many metal elements on this sword, and they are coordinated and reasonable. Experts have been unable to solve its metal memory function. It can also be called the unsolved mystery of the world.

The other is the transparent mirror of the Western Han Dynasty, which belongs to the national first-class cultural relics and is now collected in Shanghai Museum. Why is it called Tongtian Mirror? Because if there is strong light shining on its front, the pattern on its front will be mapped to the wall through its back, which is a great technology. I think Premier Zhou personally ordered me to find out this principle. Although the principle of light transmission is generally clear, it is not an easy task to rebuild such a mirror, and I am afraid it will take a long time.

Finally, the bronze plate, known as "the first dish in the world", is also a treasure against the sky. The dragon and dragon on this statue plate symbolize the princes and are the treasures of Zeng's country. Its casting skills were lost in the Warring States period, and modern science and technology cannot be copied at present.

It's hard to imagine the wisdom of the ancients in China. Modern science and technology are so advanced that we can't fully understand them and worship the ancients in an instant. However, I hope our country can explore the secrets of these treasures as soon as possible and understand the wisdom of the ancients and their living conditions.
