What are the important inventions of ancient China

Four major inventions: the compass, papermaking, printing, and gunpowder.

Armillary sphere, geokinetic instrument, silkworm spinning, weaving, porcelain, pottery, ironware, football (called Keju in ancient times) and so on.

The compass, papermaking, printing, gunpowder (the four great inventions).

The four great inventions of papermaking, printing, gunpowder, and compass are the great contributions of the Chinese nation to world civilization, and the four major inventions have profoundly influenced the course of world civilization. These inventions have changed the face of the world and the original state of everything, and their impact is not limited to a certain region, but the whole world; Its impact does not last for a lifetime, but for thousands of years.

In addition to the four major inventions of papermaking, compass, gunpowder, and movable type printing, and the new four major inventions of traditional Chinese medicine, the 10-digcial value system, the equatorial coordinate system, and the new four major inventions of engraving printing, there are many ancient Chinese inventions that have influenced the development of science and technology in the world, such as porcelain, silk, metal smelting and casting, and deep cultivation.

The 24 solar terms can be called the fifth great invention in ancient China.

There have also been many new advances in physics, chemistry, biology, and so on. Our ancestors created two world-class eras in which ancient Chinese science and technology flourished.

Wait a minute...

In addition to the four great inventions, Zhuge Liang invented the early car, which was the wooden ox and flowing horse.

Compass, papermaking, gunpowder, movable type printing.

Human pox inoculation ——— modern immunology.

It is ——— modern balance ring by the incense burner.

Jiri drum car ——— modern taxi

Autumn stone ——— modern sex hormones.

Go and find the Heavenly Crafts, Mengxi Pen Talk, Qi Min's Technique, the Complete Book of Agricultural Administration, and the Theory of Heavenly Speech.

You will know these books that our country's explorations in the natural sciences have discovered and invented The four great inventions are just the tip of the iceberg, and our ancestors fought against nature Transformation is advanced.

1. Iron casting.

In the 4th century BC, the Chinese invented iron casting. Blast furnaces were already used to cast iron in China at least in the 4th century BC. In addition, coal, which can provide high temperatures, has been used as a fuel since the 4th century, or earlier.

Cast iron was widely used in the late feudal period as agricultural tools (such as ploughs and plough mirrors), prison basins for boiling salt, iron cannons, and artistic castings. In the 10th century AD, it was possible to cast extra-large iron castings weighing up to 50 tons (such as the iron lion in Cangzhou, Hebei). After five dynasties, iron buildings increased, such as the Northern Song Dynasty Iron Tower in Dangyang, Hubei.

2. Papermaking is an important invention of the working people of ancient China. There are two forms: mechanical and manual. The mechanism is to continuously carry out on the paper machine, dilute the pulp suitable for the paper quality to a certain concentration with water, preliminarily dewater the net part of the paper machine, form wet paper sheets, and then press and dehydrate, and then dry into paper.

By hand, a frame with bamboo curtains, polyester mesh or copper mesh is used to copy the fibers scattered and suspended in water into wet paper pages, which are pressed and dehydrated, and then dried or dried into paper.

3. Compass.

The compass is the result of the understanding of magnetism by the ancient Chinese working people in long-term practice. As one of the four great inventions of ancient China, its invention has played an immeasurable role in the development of human science and technology and civilization.

In ancient China, the compass was first used for rituals, ceremonies, military affairs, divination and feng shui to determine directions. It is commonly used in navigation, geodesy, travel and military applications. There are three types of components for the compass that physically indicates the direction, namely the Sinan, the compass and the magnetic needle, all of which belong to Chinese inventions.

4. Gunpowder. It is a substance that can burn rapidly and regularly under the action of appropriate external energy, and at the same time generate a large amount of high-temperature gas. In the military, it is mainly used as the propellant of guns and shells, the propellant of rockets, missiles and other driving devices, and is an important part of ammunition.

An outstanding achievement in the history of civilization. Gunpowder has become one of the important inventions of human civilization because of its lethality and deterrence, bringing human beings the role of stopping war and security defense.

5. Printing.

Block printing was invented in the Tang Dynasty and was widely used in the middle and late Tang Dynasty. During the reign of Emperor Renzong of the Song Dynasty, Bi Sheng invented movable type printing, marking the birth of movable type printing. He was the first inventor in the world, marking the birth of movable type printing about 400 years before the German Johannes Gutenberg's movable type printing.

Printing is the forerunner of modern human civilization and has created conditions for the wide dissemination and exchange of knowledge. Printing was spread to Korea, Japan, Central Asia, West Asia and Europe.

Movable type printing, papermaking.

There were many major inventions and creations in ancient China, and here are a few of them:

1.Papermaking: Papermaking is one of the most important great inventions in China, which was invented by Cai Lun during the Eastern Han Dynasty (105 AD) and is the predecessor of the modern paper manufacturing industry.

2.Compass: The magnetic effect of the compass is an advanced technology in ancient China for making beams and filial piety, invented around 1000 AD, and was used for navigation, direction, and position measurement.

3.Gunpowder: Gunpowder was invented by the Chinese during the Tang Dynasty (9th century AD), initially for alchemical purposes, and then used in warfare, economy, culture, etc., playing an important role.

4.Movable Type Printing: Movable type printing was invented during the Ming Dynasty in China, appearing between 1041-1048 AD, and it is considered a major advance in printing, helping to promote cultural exchange and the spread of knowledge.

5.Porcelain: Ancient China invented the technique of porcelain making, which is a very high-quality and beautiful ceramic product that has become one of the important representatives of Chinese culture.

6.Acupuncture: Ancient China invented acupuncture technology, which is a method of disease and is widely used in the field of traditional Chinese medicine.

These inventions and creations not only had a profound impact on Chinese society at that time, but also played an important role in promoting the development of human civilization as a whole.

Papermaking, the compass, gunpowder, and printing.

The four great inventions of ancient China refer to papermaking, compass, gunpowder and printing, papermaking and printing have greatly promoted the spread and development of social culture, gunpowder is the predecessor of guns and cannons, and the socks and potato compass have made great contributions to the navigation industry in China and even the world.

Needless to say, the four major inventions are needless to say.
