Personally, I think it's the second one.

I think the second one is right.

Papermaking is one of the four great inventions in ancient China, and now it is generally used to make paper with reeds and wood.

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.

China is the first country in the world to raise silkworms and weave silk. In ancient China, the working people of the superior silkworm cocoons drew silk and weaved silk, and the remaining evil cocoons and disease cocoons were made of silk cotton by bleaching method. After the bleaching is completed, there will be some residues left on the mat.

When the number of bleaching is too much, the residue on the mat will accumulate into a layer of fiber flakes, which can be peeled off after drying, and can be used for writing.

The meaning of papermaking

After having words, the most important thing is to have a good carrier. The ancient Egyptians used the papyrus of the Nile to tell history; In ancient Europe, people also used animal skins such as sheepskin to write for a long time; In China, before the invention of papermaking, oracle bones, bamboo slips and silk silk were used for writing and recording in ancient times.

However, the oracle bones and bamboo slips are relatively bulky, and Qin Shi Huang has to read a whole car just to read the chapters a day; Although silk silk is lightweight, it is very expensive and not suitable for writing. In the Han Dynasty, due to the rapid economic and cultural development of the Western Han Dynasty, oracle bones and bamboo slips could no longer meet the needs of development, which prompted the improvement of writing tools - paper was invented.

Papermaking is an important chemical process, and the invention of paper is a very valuable contribution made by China in the spread and development of human culture, a major achievement in Chinese history, and has also had an important impact on Chinese history.

Generally, with reeds and wood.

Papermaking shows Hu Xianglu's spirit of being aggressive, innovative, exploratory, and not afraid of failure. Papermaking is one of the four major inventions in our country, it is improved by Cai Lun, so it is also called "Cai Hou paper". The following is an introduction to the specific content of "what spirit of the ancients is expressed in papermaking".

1. Aggressive: When there is no paper, people can only use a knife to engrave words on bamboo, which is very inconvenient, and it is precisely because of the positive and enterprising spirit that they will look for better alternatives.

2. Be brave in innovation: innovation is very difficult, and people often fall into a fixed mode of thinking, so papermaking is a very great invention.

3. Have the courage to explore: When Cai Lun improved papermaking, he had no experience from his predecessors, and could only explore a new path by himself.

4. Not afraid of failure: Any invention and innovation is accompanied by countless failures, and the spirit of not being afraid of failure can complete the innovation.

The emergence of ancient papermaking has greatly facilitated the spread of people's culture, and many words and events have been recorded. Through the above article, I believe everyone knows the answer to the question "What spirit did papermaking show the ancients". In general, the emergence of papermaking is of great help to China's historical civilization, it accelerates the speed and convenience of civilization spread, so that more people can learn words.

The invention of paper describes the invention process, spread and influence of Chinese papermaking.

It describes the advantages of papermaking, praises the wisdom of Cai Lun and other ancient people, clarifies the great contribution of papermaking to world civilization, and embodies national pride.

The invention of papermaking is one of China's great contributions to world civilization.

About 1,900 years ago, in the Eastern Han Dynasty, there was a man named Cai Lun, who absorbed people's long-accumulated experience and improved papermaking. He cut or cut off raw materials such as bark, hemp, straw, and rags, and soaked them in water and mashed them into pulp; Then the pulp is fished out and dried, and it becomes a kind of paper that is both light and easy to use.

China's papermaking technology first spread to the neighboring Korean Peninsula and Japan, and later to the Arab world and Europe, which greatly promoted the progress of human society and cultural development, and influenced the whole world.

The invention of "papermaking" has greatly improved the convenience of writing in ancient China, so once it was invented, "papermaking" was added to one of the "four great inventions" in ancient China, surpassing many ancient inventions.

"Papermaking" has a deep origin, it is recorded that it first appeared in the Western Han Dynasty, which is very rich in culture, but the original paper is only made of hemp fiber or hemp fabric, and because papermaking is still in the early stage, the process is very simple, so the paper produced is also rough in texture, and there will be a lot of fiber bundles that are not loose in the middle, the surface is extremely unsmooth, and the most important thing is that it is not suitable for writing, and can only be used for packaging.

Really make "papermaking" famous all over the world should also be counted, the Eastern Han Dynasty Cai Lun improved papermaking, Cai Lun using bark, hemp and cloth, fish nets and other raw materials, through frustration, pounding, frying, baking and other processes for the production of paper, it is the origin of modern paper. Because of the fact that the paper is easy to find, cheap, and has significantly improved quality, it is becoming more and more widely used. Therefore, in order to commemorate Cai Lun's achievements in improving papermaking, later generations called this kind of paper "Cai Hou paper".

After Cai Lun's transformation of paper, the later paper is about all derived from this process, and there is no special change. This is the origin of "papermaking".

The invention of papermaking technology has accelerated the development of China's cultural undertakings, and because the paper was transmitted to Korea, Japan, India and Arabia and other countries in the later period, it was transmitted to Europe through North Africa, it greatly promoted the popularization of world cultural exchanges and education, and had a very positive and far-reaching impact on the development of human culture, it is a great contribution of Chinese civilization to world civilization. In general, before the invention of papermaking, oracle bones, bamboo slips and silk silk were used in ancient times to write and record materials, but because the cost is very expensive, it is not suitable for writing, so the invention of paper is a valuable contribution, a major achievement in Chinese history, and one of the famous "four great inventions" in China.

Originated in the Western Han Dynasty in China, it has influenced the development of literature in China, promoted social progress, and promoted the process of history.

It originated in the Western Han Dynasty. It has promoted the development of cultural undertakings, and has also spread to other countries, promoted the exchange of world cultures, promoted the development of world education, and also had a far-reaching impact on cultural undertakings, which is a progress of Chinese civilization.

It originated in the Song Dynasty in China. Let's have books to read now. Avoid cutting down trees. It has contributed to the country's economic development and cultural progress.

In the first year of Yuanxing in the Eastern Han Dynasty (105), Cai Lun improved papermaking. He used tree bark, hemp and cloth and fish nets and other plant raw materials to make paper through the process of frustration, pounding, copying, and baking, which is the origin of modern paper. This kind of paper, which is easy to find raw materials, is very cheap, and the quality has also improved, and it is gradually becoming more popular.

In order to commemorate Cai Lun's achievements, later generations called this kind of paper "Cai Hou paper". Paper is a sheet of fiber products used for writing, printing, painting, packaging, etc. Generally, it is made of the water suspension of plant fibers that have been pulped and staggered on the Internet, preliminarily dehydrated, and then compressed and dried.

China was the first country in the world to invent paper. According to archaeological findings, during the Western Han Dynasty (206 BC to 8 BC), there was already hemp fiber paper in China. The texture is coarse, and the quantity is small, the cost is high, and it is not popular.

Cai He used linen, broken fishing nets, and rotten wood to soak in water for a few days when making paper, and later switched to bamboo to make paper.
