Why is Cai Lun improving papermaking, not inventing papermaking?

Because there has been a technology of using raw materials such as cotton wool to make paper, because of the high cost, it is difficult to promote, Cai Lun will improve the papermaking technology, use cheap materials, and greatly reduce the quality of paper.

This is because paper has appeared before Cai Lun, but this kind of paper is very rough and the manufacturing cost is very high, so it is very difficult to popularize.

Because China has had paper for a long time, and Cai Lun has only improved paper to make it easier to use, so it will not be said that he invented papermaking.

Because there is archaeological evidence that papermaking has long existed, Cai Lun later improved papermaking.

Because papermaking already existed before Cai Lun, but it was better after him, it cannot be said to be an invention.

<> Cai Lun. Papermaking was invented.

Wrong. It was Cai Lun who improved the paper. Papermaking is one of the four great inventions of China.

One of them was invented in the Western Han Dynasty of the Han Dynasty, and the improvement period was in the Eastern Han Dynasty of the Han Dynasty. Paper is the crystallization of the long-term experience and wisdom of the ancient Chinese working people, and it is an outstanding invention in the history of human civilization.

Paper is the crystallization of the long-term experience and wisdom of Chinese working people, paper is a sheet fiber product used for writing, printing, painting or packaging. 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.

Cai Lun is to improve and advance the art of papermaking.

Because the earliest inventor has no historical records, it should be searched in the Western Han Dynasty, China already has paper that can be written, Cai Lun is a eunuch in the Eastern Han Dynasty, he improved the papermaking technology, so that the cost of paper has been reduced, and it is easier to write, which is conducive to the popularization of paper, and his improved paper, known as "Cai Hou paper".

Cai Lun, who supervised the manufacture of all kinds of utensils used in the palace, picked out tree bark, broken linen, old fishing nets, etc., and asked the craftsmen to chop them up and soak them in a large pool, and after a while, the debris in them rotted, and the fibers were not perishable, so they were retained.

He then asked the craftsmen to scoop up the soaked raw materials, put them in a stone mortar, and keep stirring until they became a slurry, and then use bamboo strips to pick up this sticky thing, and when it was dry, it became paper.

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.

Cai Hou paper

Cai Lun, who was improving papermaking, supervised the manufacture of various utensils used in the palace. He picked out tree bark, torn linen, old fishing nets, etc., and asked the craftsmen to chop them up and soak them in a large pool. After some time, the debris in it rots, while the fibers are not perishable and are retained.

He then asked the craftsmen to scoop up the soaked raw materials, put them in a stone mortar, stir them constantly until they became a slurry, and then pick up the sticky thing with bamboo strips, and when it was dry, it was removed and turned into paper. Cai Lun led the craftsmen to repeatedly try and test, and tried to produce paper that is not only light and flexible, but also easy to use, wide and inexpensive.
