The landlord should ask about paper in the real sense, of course, in China, Cai Lun used fabric, tree bark, to create a paper that is still in use today. As for the rest, before there was paper, China used bamboo and wood tablets and silk cloth, Westerners used sheepskin and wood, and Egyptians used papyrus, which was a kind of leaf and could not be counted as paper.

Papermaking is one of the four great inventions of China and an outstanding invention in the history of human civilization. China is the first country in the world to raise silkworms and weave silk. The ancients used the best silkworm cocoons to draw silk and weave silk, and the remaining evil cocoons and sick 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 number of by-products of this drifting is not large, and it is called Helang or Fang Fu in ancient books.
This shows that the origin of Chinese papermaking is related to silk wool.
History. 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.
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. Since ancient times, the Chinese have known how to raise silkworms and reel silk.
During the Qin and Han dynasties, the handicraft industry of making silk cotton from secondary cocoons was very popular. This method of processing the cocoon is called the bleaching method, and the basic points of the operation include repeated beating to mash the silkworm clothes. This technology later developed into pulping in papermaking.
In addition, in ancient China, lime water or grass and wood gray water were commonly used to degum silk and linen, and this technology also inspired the degumming of plant fibers in papermaking. Paper was developed with the help of these technologies. There is very little historical literature on the papermaking technology of the Han Dynasty, so it is difficult to understand its complete and detailed process.
Although later generations have speculated, it can only be used as a reference. In general, there are many links in papermaking technology, so there must be a process of development and evolution, which is by no means the work of one person. It is the crystallization of the long-term experience and wisdom of the working people of our country.

China. Archaeologists have found fragments of Western Han paper in Han Dynasty sites and tombs in Xinjiang, Shaanxi, Gansu, Inner Mongolia and other places. The discovery of these paper scraps shows that the writing paper, silk, bamboo, and wood paper were invented in the early Western Han Dynasty, and the four kinds of writing utensils were used in parallel in the Western Han Dynasty.
During the Eastern Han Dynasty, Cai Lun created an innovative idea of using bark, hemp, rags and old fishing nets to process new writing materials--- paper, which was presented to Emperor He of the Han Dynasty in the first year of Yuanxing. The emperor appreciated his ingenuity and named him Hou, and since then this paper has been called "Cai Hou paper".

China. In the general understanding, many people think that Cai Lun invented papermaking in the Eastern Han Dynasty, and the earliest was on paper. But now archaeological discoveries have also found that there is already paper in the Western Han Dynasty, which proves that it is the Mawangdui No. 1 tomb group.
This is in the history textbooks of high school now. The purple one. Talking about cultural history. can be found.

China. There was the earliest paper in the Western Han Dynasty, and Cai Lun in the Eastern Han Dynasty improved papermaking.
-
In China, there was rough paper in the Western Han Dynasty, and after Cai Lun improved papermaking in the Eastern Han Dynasty, paper was widely used.

It is China, the Song Dynasty.

One of the four great inventions of China at the time of papermaking...
-
Since it is the earliest paper, whether it is rough or not, it meets the definition of paper: the earliest paper made of plant fibers, lightweight, foldable and curly, and able to record words.
1. The earliest paper in the history of the world: 5,600 years ago, papyrus used in Egypt. At least 200,000 volumes of Egyptian papyrus literature are preserved in Egypt and museums smuggled into various countries.
2. The earliest paper in China: 2200 years ago, it existed in the early Western Han Dynasty, but it was still very rough and not widely used. In 105 AD, after the improvement of Cai Lun in the Eastern Han Dynasty, it is considered to be the originator of modern papermaking.
-
Mainly because the paper of ancient Egypt and the paper of today are not the same thing, and the manufacturing process of Chinese papermaking is more complex than that of ancient Egypt.
-
Because our production method is different from theirs, some of our paper is more easy to use, so it is one of our four major inventions.
-
Because China's papermaking technology has a particularly great influence and has had a profound impact on the world.

The world's earliest paper appeared in the Western Han Dynasty in China, the quality is rougher, can not be used for writing, after the improvement of Cai Lun in the Eastern Han Dynasty, the production of plant fiber paper, this paper is light, low, at the same time to reach the level of writing, is widely used, this paper is called "Cai Hou paper".
The world's earliest paper appeared in the Western Han Dynasty in China. Paper from the early Western Han Dynasty (206 BC – 23 AD) excavated from the Fangmatan Han Tomb in Tianshui, Gansu Province, China, is the earliest paper that has been discovered.
In addition, the ancient paper of the Western Han Dynasty has been unearthed in Dunhuang Maquanwan Fengsui Ruins and Dunhuang Sweet Water Well, Han Hanging Spring Post Site and other places. But these papers are coarse, of poor quality, and cannot be used for writing.
The paper made by the working people of the Western Han Dynasty was improved by Cai Lun of the Eastern Han Dynasty to create a plant fiber paper that reached the practical level of writing, called "Caihou paper".
Cai Hou paper has been able to meet the requirements of writing.
For Cai Lun, the purpose of improvement is to replace the wood, bamboo, silk and other writing, recording materials, due to the advantages of light paper, low quality, has been widely used, become the main writing materials.
Papermaking is arguably the greatest invention in human history! Because of the emergence of papermaking, the culture can be better passed on, and the heaviness of bamboo slips can be thrown away, so that people can gain knowledge on light books.

At present, the earliest paper in the world is from the Western Han Dynasty. Paper is the crystallization of the long-term experience and wisdom of Chinese working people, and is a sheet fiber product used for writing, printing, painting or packaging. It is made by the staggered combination of pulping plant fiber aqueous suspension, preliminary dehydration, compression and drying.
China was the first country in the world to invent paper.
During the Wei, Jin, Southern and Northern Dynasties, paper was widely spread, generally used by people, papermaking technology was further improved, and the papermaking area was concentrated in Luoyang, Henan Province before the Jin Dynasty and gradually spread to Vietnam, Shu, Shao, Yang and Anhui, Jiangxi and other places, and the output and quality increased day by day. The raw materials for papermaking are also diversified, and there are many types of paper. Such as bamboo curtain paper, the paper surface has obvious lines, and the paper is tight and thin.
There is rattan paper made of rattan bark as raw material, the paper is uniform and smooth, white as jade, and does not leave ink. Dongyang has fish roe paper, also known as fish paper, which is soft and smooth. Jiangnan uses straw and wheat straw fibers to make paper, which is yellow in color and has a rough texture that is difficult to write.
In the north, mulberry stem bark fiber grinding is used to make paper, with excellent texture, white color, light and soft, strong tensile force, and the paper grain is torn off like cotton silk, so it is called cotton paper.
In order to prolong the life of paper, the Jin Dynasty has invented a new technology of dyeing paper, that is, to boil the juice from the yellow tiller, dip and dye the paper, some write first and then dye, and some blindly sell the liquid first and then write. The dyed paper is called dyed paper, which is naturally yellow, so it is also called jute paper. Yellow paper has the function of insect control and mothproofing.
By the Jin Dynasty (4th century), paper had finally replaced silk slips as the main writing material. Cai Lun played a great role in promoting the production of hemp paper and leather paper buckets, although he was not the inventor of papermaking, but his historical position as a technological innovator and organization promoter should be recognized.

There are eggs first, and then there are chickens, and the predecessor of the chicken also reproduces by laying eggs, and it is laid and laid, and suddenly a chicken hatches in the egg, so the chicken appears. The predecessor of the chicken was called the Archaeopteryx chicken, and the eggs laid by the Archaeopteryx were called the Archaeopteryx eggs. The predecessor of the Archaeopteryx was supposed to be some kind of reptile that could fly, and they also laid eggs, so there were eggs first, and chickens later. >>>More
