The four great inventions of ancient China were finally completed in

The four great inventions of ancient China were finally completed in the Song Dynasty.

Papermaking: Improved by Cai Lun in the Eastern Han Dynasty. On the basis of summarizing the experience of his predecessors in making silk weaving crystals, Lun used tree bark, broken fishing nets, rags, hemp and other raw materials to manufacture plant fiber paper suitable for writing, and improved papermaking technology to make paper a commonly used writing material.

It is known as "Caihou paper".

Gunpowder: Gunpowder was invented by Han Chinese alchemists in the Sui and Tang dynasties, more than 1,000 years ago. The study of gunpowder began with the ancient Taoist alchemy, the ancients refined the elixir in order to seek immortality, the purpose and motivation of alchemy were advanced, but its experimental methods still had merit, and finally led to the invention of gunpowder.

Printing: It is reported that Bi Sheng invented clay movable type printing during the Northern Song Dynasty, which is considered to be the earliest movable type printing technology in the world. Shen Kuo, a scientist and politician in the Northern Song Dynasty, once wrote an article called "Trapboard" in "Mengxi Pen Talk", which introduced the whole process of trapboard printing in detail, which was easy to understand and very detailed.

Compass: There are records of compass cars in the time of the Yellow Emperor, the earliest compass ("Sinan") appeared in the Warring States period, and the compass was used for navigation in the Northern Song Dynasty and Song Dynasty.

Surname. Papermaking was perfected in the Eastern Han Dynasty, gunpowder was widely used in the Tang Dynasty, the compass (or compass) was used for navigation in the Song Dynasty, and Bi Sheng invented movable type printing in the Northern Song Dynasty.

Movable type printing was invented by Bi Sheng of the Northern Song Dynasty.

Papermaking was improved by Cai Lun of the Eastern Han Dynasty. Gunpowder was invented in the process of alchemy, and the earliest gunpowder ** appeared in the late Tang Dynasty called "Flying Fire".

The invention of the southern needle was too early, there were already records of the compass car in the Yellow Emperor, the earliest compass ("Sinan") appeared in the Warring States period, and the compass was used for navigation in the Northern Song Dynasty and Song Dynasty.

Most of the four major inventions were improved and developed in the Song Dynasty, and not all of them were produced during that period, because the Song Dynasty was a dynasty of Chinese light martial arts, so there were many inventions and creations. However, it is precisely because of this that the troops behind are too weak and are invaded by the Jin. There are pros and cons

The four major inventions, which are important creations of the working people in ancient China, refer to papermaking, the compass, gunpowder and printing.

This statement was first put forward by the British sinologist Joseph Eyjo!

1.The compass, also known as Sinan, is often used in navigation, geodesy, travel and military affairs. 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.

According to the records of the "Ancient Mine Record", it first appeared in the Cishan area during the Warring States Period.

2.Papermaking is one of the four great inventions in China, paper is the accumulation of long-term experience and wisdom of ancient Chinese working people, it is an outstanding invention in the history of human civilization. In the first year of the Eastern Han Dynasty and Emperor Yuanxing, that is, in 105 AD, Cai Lun made plant fiber paper suitable for writing on the basis of summarizing the experience of his predecessors in manufacturing silk weaving crystals, and improved papermaking technology to make paper a commonly used writing material.

3.Gunpowder was invented by ancient Chinese alchemists in the Sui and Tang dynasties, more than 1,000 years ago. The study of gunpowder began with the ancient Taoist alchemy of the ancients, who refined the elixir in order to achieve immortality, which eventually led to the invention of gunpowder.

4.Movable type printing is an ancient printing method, and the clay movable type invented by Bi Sheng in China during the Northern Song Dynasty and Qing Dynasty marked the birth of movable type printing. He was the first inventor in the world, about 400 years before the German Johannes Gutenberg movable type printing.

The four great inventions of ancient times were very powerful and were used by people abroad.

Papermaking, printing, gunpowder, and the compass.

The so-called four great inventions refer to the four inventions that had a great influence on the world in ancient China, namely papermaking, the compass, gunpowder, and movable type printing. The term "Four Great Inventions" was first proposed by the British sinologist Joseph Needham, and was later inherited by many Chinese historians. These inventions were transmitted to the West through various channels, thus exerting a huge impact on the development of world civilization.

A compass is a simple instrument used to determine directions. Its predecessor was Sinan. Its main component is a magnetic needle mounted on a shaft that can be rotated freely.

The magnetic needle can remain in the tangent direction of the magnetic meridian under the action of the geomagnetic field. The north pole of the magnetic needle always points to the south pole of geography, and people can use this performance to discern the direction. The compass was commonly used in navigation, geodesy, travel, and marching operations.

This marketing is very big, because this thing has a certain impact on the whole world and promotes the development of the world.

China's four major inventions have influenced the whole world, and an item has been invented, which has made the Western aristocracy rob the head.
