What are China s four major inventions? How did they come up with the idea to invent these?

Papermaking, printing, gunpowder, compass. This is not the invention of one person, but the result of the practice of many people after a long period of accumulation. Papermaking, printing, because there is a practical need to expand the spread of culture, gunpowder is an accidental discovery of Taoist alchemy, the compass invention background is unknown, but the Northern Song Dynasty has a prototype.

Papermaking, printing, gunpowder, compass. This is the working people's long-term accumulation of life, and gradually formed a perfect technology. It is the crystallization of the great wisdom of the Chinese people.

At a certain time, everyone will always have their own experience.

The four great inventions of ancient China resounded all over the world. Pai Chung Cai Lun invented papermaking, Bi Sheng invented printing, Sina and the inventor of gunpowder are not clearly recorded in history. The four major inventions have promoted social progress and provided convenience to society.

The Four Great Inventions predate Western countries by several hundred years.

One. Cai Lun

Cai Lun invented papermaking. Paper, also known as the Four Treasures of the Study, is used to record things. At first, humans used oracle bone inscriptions, and later bamboo slips were used to sing the word dust.

With the progress of society, the quality of paper has also changed, from coarse paper to delicate paper. The paper made by Cai Lun was more delicate and of better quality than before, and later became known as Cai Hou paper.

Two. Bi Sheng

Bi Sheng invented the printing press. Nowadays, printing with a machine is very simple. However, in ancient times, printing was very troublesome.

It is necessary to have a word model and then arrange the models according to the content of the manuscript. Inking and printing paper are still troublesome. Movable type printing in the Northern Song Dynasty was invented 400 years earlier than in Western countries.

Three. Sun Simiao

The gunpowder was probably discovered by Sun Simiao by accident when he was refining pills. It appeared in the Sui and Tang dynasties, more than a thousand years from today. People in ancient alchemy knew some chemical knowledge, and these chemical elements would be heated in a furnace.

Later, the Chinese used gunpowder to make firecrackers, and the Westerners used gunpowder to make **.

Four. Shen Kuo

Historically, Zhang Heng invented the South Compass, which Shen Kuo improved and became the Compass, also known as Sinan. The ingredients used to make it are very simple, just use a magnetic needle. The compass appeared during the Warring States period, and the compass continued to improve.

Because the compass continues to evolve, it has also managed to become one of the four great inventions. The four great inventions are the crystallization of the wisdom of the ancient people. Their inventions contributed to political, cultural, and economic development.

These inventions spread to the West and contributed to the development of world civilization. The industriousness and wisdom of the ancient Chinese people are something that people need to learn now. There were many inventors in ancient China, and their products were beneficial to the development of society.

The Chinese were stronger than the world in ancient times, and now China is still the lion of the East.

Bi Sheng, movable type printing Ling Jing Brush In China, about the beginning of the Tang Dynasty in the 7th century AD, there were books printed using block printingThe "Diamond Sutra" printed in the ninth year of Tang Xiantong (868) is the earliest existing print in the world with the time of Qingwang engraving. During the reign of Emperor Renzong of the Song Dynasty, Bi Sheng, a commoner, invented movable type printing on the basis of the popularization of engraving printing.

Cai Lun, papermaking, the first year of Yuanxing in the Eastern Han Dynasty (105).

Gunpowder was invented by ancient Chinese alchemists in the process of alchemy, there is no specific, gunpowder began to be invented in the Three Kingdoms era, it was used as firecrackers at that time, and it was used as a military reputation in the Song Dynasty.

There is no specific inventor of the compass The Chinese ancestors have used natural magnets to make Sinan spoons to indicate the direction. During the Three Kingdoms Wei period, Ma Jun used magnets and differential gears to create a mechanical device that could indicate the direction - the guide car. Shen Kuo, a scientist of the Song Dynasty, recorded the method of making a magnetic needle for pointing in his "Mengxi Bi Tan".

Later, it was developed into a compass that integrated a magnetic needle and an azimuth disk.

Cai Lun Cai Lun invented papermaking, paper is also known as the four treasures of the study, used to record things, at the beginning of human beings with oracle bones, and later the use of bamboo slips, social progress, the quality of paper has also changed.

1. The four major inventions, namely papermaking, compass, gunpowder and printing, are the four inventions that had a great impact on the world in ancient China.

2. Papermaking: Cai Lun improved, also known as "Cai Hou paper", he summed up the silk experience of his predecessors, changed the raw materials, changed the bark, broken fishing nets, rags, hemp heads, etc., to create a plant fiber paper suitable for writing. Historical significance:

Papermaking was introduced to Japan via Korea in the 7th century, to the United Arab Emirates in the mid-8th century, and in the 12th century, Europe began to set up paper-making factories following the Chinese approach. It has a far-reaching impact on the development of the world's paper industry and the spread of human culture, and its contribution is immeasurable.

3. Compass: It is the crystallization of the ancient working people, the inventor has no way to study, but the clues can be found from a large number of historical documents, during the Warring States Period, there are guide tools Sinan, in the Spring and Autumn Period, people can make nephrite and jadeite into Sinan, and Wang Chong's writings in the Eastern Han Dynasty are also recorded, and Shen Kuo's supplementary pen talk in "Mengxi Pen Talk" talked about various phenomena produced when the friction method is magnetized. Historical significance:

There has been a great development of productive forces, especially agricultural production, which has led to the development of mining and smelting. In the long practice of production, people used the compass to sail and opened up the world market, while the Europeans established a large number of colonies.

4. Gunpowder: The invention of gunpowder is a long-term alchemy for people, seeking the elixir of life, and constantly experimenting, and it has a history of more than 1,000 years. Historical significance:

China's gunpowder has promoted the process of world history, Engels once spoke highly of China's pioneering role in the invention of gunpowder, gunpowder shook the feudal rule of Western Europe, the knight class that relied on cold weapons to show off its might in the past has gradually declined, the invention of gunpowder has greatly promoted the process of historical development, and is one of the important pillars of the European Renaissance and the Reformation.

5. Printing: Now the popular version believes that Bi Sheng is the inventor, the crystallization of the wisdom of the ancient Chinese working people, and the engraving 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.

Although movable type printing appeared in the Song Dynasty, it was not widely used. Historical significance: China's wooden type technology was introduced to Korea and Japan in the 14th century, and the Korean people created copper movable type on the basis of wooden type, which was introduced to Europe through Xinjiang, and at that time Persia accelerated the development of European culture, the Renaissance appeared, and Japan became the second country in the world to use printing technology.

It is the most glorious chapter in the history of mankind, promoting the popularization of education and the popularization of knowledge, and the advanced ideas of mankind can be handed down.

1. Papermaking.

Papermaking was invented by Cai Lun in the Eastern Han Dynasty, and Cai Lun could only replace bulky bamboo slips since his invention.

On the basis of the grain paper of the bark of the Han Dynasty, rattan paper made of rattan bark appeared in the Jin Dynasty, and papermaking was prevalent in the Tang Dynasty.

because tang taizong li shimin was fond of wang xizhi's orchid pavilion preface , zhang yanyuan said :"good deeds should be prepared with 100 pieces of rice paper and wax for copying. in ancient times , it was good to paint on the couch , and it was seven or eight out of ten , without losing its brilliance .

( Records of Famous Paintings of the Past ( Volume 2 ) ) On the Use of Painting Writing " According to Yan Yuan's method , the art of copying is not only used for characters , but also for painting ; The paper used should not only be thin , but also waxed. Whether it is used for space or painting, and whether the paper used is inherently light or waxed, it must have a certain degree of clarity, and there is no doubt about it. Papermaking, once again in the battle between the Tang Dynasty and the Arabs, the leadership of Tang Xuanzong was defeated, so that the Tang army was defeated, and the Great Food (Arabs) won the battle, and there were paper-making workers in the captured Tang army, so the Arabs also learned how to make paper, which promoted cultural exchanges.

2. Printing.

China's printing technology, divided into movable type printing and engraving printing, printing flourished in the Song Dynasty, at the beginning of the first invention of engraving printing, but, the Song Dynasty's Bi Sheng, thought, why the same word to be repeated carving? Therefore, this kind of movable type printing was invented, movable type printing, and then typesetting is very convenient, and it can be removed and placed elsewhere, which is very convenient, therefore, printing has been evolving, and it has become today's convenience.

This is the engraving of engraving printing.

3. Compass. The compass is a navigation system at sea that can guide the way, and because of the compass, it evolved into today's compass. After the invention of the compass was widely used in the military, as well as navigation, the compass was also in the Song Dynasty for the heyday, the Song Dynasty was a dynasty that emphasized literature and light military force, many civilizations began from this, even the compass is no exception, the invention of the compass, so that the route of the sea is clear at a glance, but also improve the accuracy and safety of navigation.

4. Gunpowder. Gunpowder was invented from the Three Kingdoms era, when it was used as firecrackers, and was used as military use in the Song Dynasty, gunpowder is made of saltpeter with sulfur and charcoal, which can be used as cannons, muskets, etc., and the use of gunpowder can be used to dig mountains, dig walls, dig holes, as firecrackers, or as military **.

After the 14th century, Europeans learned about gunpowder from the Arabs and learned how to make firearms, and gunpowder was officially introduced to Europe.

Namely, papermaking, compass, gunpowder, movable type printing.
