History is created by man, and no one is without the world. How much of our food, clothing, shelter and transportation today comes from the wisdom of our ancestors, and we no longer have poetry, songs, and paintings. It was an unparalleled era, and what they learned realized what they did, and what they did laid the foundation for today's China. Dream back to that year, China's four major inventions attracted the world's attention. There are compasses, papermaking, gunpowder, printing.
These inventions are not only for the benefit of one people, but for the benefit of the whole human race. This is not a divine gift, this is an invention that people have worked tirelessly to change society from scratch. I believe that each of us has infinite possibilities, so have you ever fought for something? After fighting, you are the monster who started your own business on the way to the scriptures.
In addition to the four major inventions, do we have any other inventions? Yes, and many more.
1. Steelmaking method
In 120 BC, Chinese invented the method of steelmaking with pig iron, also known as the "hundred smelting method". The West did not start making steel with pig iron until 1856, about two thousand years later than China. Although the technology has advanced now, the technology is still used in some places.
2. Bronze caliper
Calipers are a fairly sophisticated measuring tool, and it is said that the 19th-century British mathematician Jonier Bill invented the earliest calipers. In fact, in the Eastern Han Dynasty more than two thousand years ago, people have begun to use calipers, and they are strikingly similar to the calipers people use today.
3. Tenon design
This is probably the darkest technology I've ever seen, and modern technology can't catch up. Its great thing is that it can make things firmly shape without a nail without glue, forming a natural beauty. Representative buildings such as the Shanxi Hanging Temple, built more than 1,400 years ago, and the Wooden Pagoda of Yingxian County, Shanxi, which is about 1,000 years old. Be amazed by the wisdom of the ancients!
4. Yue Wang Gou Jian Sword
The Yue Wang Gou Jian sword was unearthed in the Wangshan Chu Tomb Group in Jingzhou, Hubei Province, and eight characters were engraved on the sword, "Yue Wang Jiu Shallow, Self-Acting Sword". Through interpretation, experts proved that this sword is the legendary Yue Wang Gou Jian sword, which lasted for thousands of years without rust and has the function of metal memory.
5. Acupuncture
It is believed that Chinese have been using this treatment for much longer than the written history of the subject in 2000. Chinese believe that the act of puncturing the skin can cure all types of diseases that a person suffers from. Many modern doctors scoff at the idea of acupuncture, but millions of people around the world still use it.
6. Porcelain
Invented in the Sui Dynasty, this technique was perfected in the Tang Dynasty and reached its peak during the Song Dynasty. Porcelain also became a symbol of China. It has been used to this day and is widely used and widely used.
7. Iron plow
During the Han Dynasty, iron push plate plow rakes were widely used in China's agriculture. Through the adjustment of the struts, the distance between the blade and the beam can be effectively changed, and the depth of the plough can be precisely set. This technology did not reach England and the Netherlands until the 17th century. In China, this arable land technology is still used today.
The wisdom of the ancients is truly incomparable. If the ancients had traveled back to the present, their inventions could have won the Nobel Prize. When it comes to the current world, the number of inventions is far less than in the past, and the creativity of the present is stifled by the contemporary environment. Really, when we raise children, we must pay attention to their imagination and creativity, and do not easily deny them.
