1, drum:
Legend has it that in 3500 BC, people in China had artificial drums. In 3000 BC, drums were made by covering frames or containers with animal skins. The timpani was invented in China in the 2nd century BC.
2. Binary system:
It is said that Fuxi invented the binary system in 3000 BC. Zhouyi is one of the Five Classics and one of the oldest classics in China. According to legend, The Book of Changes was written by Fuxi, Zhou Wenwang and Duke Zhou about 3000 BC, and was revised by Kong Qiu into The Book of Changes. Modern electronic computers use binary instead of decimal. Who invented the binary system? "Yi Shu" in Zhouyi uses binary system. In other words, Fuxi invented binary.
3. Rope:
In 2800 BC, China people had mastered the technology of making hemp rope. Our people began to make ropes out of hemp fibers. By the beginning of AD, hemp fiber had become the main rope-making material in most parts of the world.
compass
4. Compass:
Legend has it that in 2700 BC, Xuanyuan, the Yellow Emperor of China, invented the compass. Huangdi used a compass to tell the direction in the fog and defeated Chiyou. According to historical records, China people used the compass as early as the Warring States Period. Han Feizi in the 3rd century BC said that "Sina" (compass) had been used in the Warring States period. 1090, China and Arab navigators began to install compasses on ships. As a navigation tool. In Europe, around 1 1 century, magnetic needles floating on the water were used to make compasses.
5, fish farming methods:
In 2500 BC, people in China already knew how to raise fish. At that time, Chinese people could artificially hatch fish eggs and feed them. In the1960-1970s, fish in Europe and America, such as frog fish, were farmed artificially.
6, equatorial astronomical instruments:
In 2400 BC, China invented the equatorial astronomical instrument.

7, decimal counting system:
China invented the decimal counting system in14th century BC. This is very important in modern science. The earliest evidence that Europeans formally adopted it was found in a Spanish manuscript in 976 AD, and China adopted it as early as BC14th century Shang Dynasty.
The Diamond Sutra unearthed in Dunhuang was printed in the Tang Dynasty (868).
8. Printing:
Printing is one of the four great inventions in China. In 868, people in China invented block printing. Diamond Sutra is a relief printing. It is a 5.25-meter scroll with pieces of wood 9 1 cm long and 36 cm wide printed on it.
In A.D. 1040, China lettering worker Bi Sheng invented movable type printing in Beijing. 1438, Genfertier (German) who lived in Gutenberg, Mainz, Germany, created a mold for casting metal letters.
1 107, China people also invented color printing. More than 600 years later, in 17 19, the color printing machine designed by LeBron in Germany was patented.
Fuhao tomb
9. Paint is the earliest plastic in the world;
China invented and used lacquerware at the latest in the 3rd century BC/KLOC-0. The tomb of "Fuhao" excavated in Anyang City, Henan Province 1976 (buried in the 3rd century1AD) is evidenced by her painted coffin. Needham said: "lacquer is probably the oldest industrial plastic known to mankind."
10, mirror:
About BC 12, China people invented the bronze mirror. China also invented the magic mirror in the 5th century. William Breg, a British crystallographer, systematically expounded the theory of magic mirror in 1932, which was about 1500 years later than China.
The magic mirror is one of the strangest things in the world. What's so amazing about the magic mirror? On the reverse side of the magic mirror, there are bronze patterns, images or figures, or both. The side reflecting light is convex, made of polished bronze and used as a mirror. Under most lighting conditions, this kind of mirror looks the same as other ordinary mirrors. However, when the mirror is used in bright sunlight, its reflecting surface can be "seen through". By reflecting sunlight on a dark wall with a mirror, people can see the patterns or words on the mirror from the images projected on the wall. Solid bronze products become transparent, which makes people feel mysterious. This phenomenon made China people give the magic mirror a name called transparent mirror.
Bronze is opaque, but it actually makes people feel transparent. Why? This mystery has been discussed by Chinese and foreign scholars for hundreds of years. China scientist Shen Huo and foreign scientist Sir William Breg both expressed their opinions. When Sir William Breg discovered this mystery in 1932, he said, "It is the amplification of reflection that makes the pattern appear clearly." Needham called all this "the first step in mastering the fine structure of metal expression."
