American patents appeared on terracotta warriors and horses, far ahead. What is the reason?

The wisdom of the ancient working people in China has been passed down to this day, which has benefited many future generations for life. Cai Lun's papermaking, Lu Bansuo, Zhuge Liang's Zhuge Liang's crossbow, etc., all brought a lot of convenience to future generations. The mausoleum of the King of Qin is very magnificent, which shocked the whole world after it was dug up, among which the most representative is the Qin Terracotta Warriors and Horses. Every terracotta warrior has its unique facial features, which makes people feel the greatness of the ancients.

It is precisely because of this important decision that no matter what hardships our country has experienced, there has never been a fault of civilization. It can be said that the emergence of Qin Shihuang is a key figure in the inheritance of Chinese civilization, and Qin Shihuang is definitely "an emperor through the ages".

Although Qin Shihuang has been dead for many years, the topic about him has never been cut off, because up to now, people still know very little about him and the Qin Dynasty, and even there are many advanced technologies of the Qin Dynasty, which will still be amazing according to today's technology. For example, today, I want to tell you about the great discovery of Qin Terracotta Warriors. This treasure is the most precious thing in the Terracotta Warriors!

1994, archaeologists found a batch of bronze swords in the second pit of Terracotta Warriors. Even after more than 2200 years, these swords are still as bright as new and extremely sharp. Qin bronze sword is 86 cm long, with slender body, ridges on both sides, four vertical points and four sharp points, which is 30 cm longer than other countries in the same period. The reason why it is so long is to strengthen the piercing nail and selectively reduce the chopping function.
