Live broadcast: Take our ancestors to see modern China

[Another method of processing paper is called coated paper.

Coated paper is made by applying white mineral powder to the surface with an adhesive or starch paste, and then polishing it.

Doing so can not only increase the whiteness and smoothness of the paper, but also reduce its light transmittance, making the paper surface tight and better at absorbing ink.

The dyeing and decoration technology during the Wei, Jin, Southern and Northern Dynasties inherited the dyeing and decoration technology of the Han Dynasty, and after development and inheritance, dyeing can increase the appearance of paper and improve its performance.

The development of technology has provided more choices for the quality and use of paper, and promoted the widespread application of paper in social life.

Watching the gradual development of the sky curtain and its inheritance from generation to generation, everyone also felt the significance of inheritance.

This is a process of creating something from scratch, followed by continuous innovation and research and development. It is the efforts of generations of people that have made daily necessities available to everyone.

[The Sui and Tang dynasties were a prosperous period for the development of papermaking in China.

As the top of the economic, political and cultural pyramid, countless men of letters and poets emerged during this period.

I believe many people can relate to this. It is impossible for us to memorize all the poems we have learned since childhood.

The development of paper naturally promoted the development of culture, which led to the famous lines written by poets and lyricists throughout the ages.

The Tang Dynasty adopted processing techniques such as dyeing and powdering, adding wax, polishing, printing, lacquering and silk working.

Continuous research and development and manufacturing have made the raw materials of paper more refined, the fiber dispersion higher, and the quality of paper has been significantly improved.

During the Sui and Tang dynasties, due to technological advances, the quality of paper was greatly improved, and it was also used in packaging, decoration, lanterns, umbrellas, textile substitutes and other fields.

When Li Shimin saw the various types of paper, he thought of the Yanteng paper they often used. At least they were much luckier than previous dynasties at this time.

The papermaking industry also appeared in various places, with a wide variety of materials that were not comparable to those in the Qin and Han dynasties.

People in the court also had businesses selling this kind of paper. Scholars needed paper, but the price was not cheap.

Now that various methods and materials for Tianmu have been revealed, we may have to look into the source of this paper in the future.

Common people got a headache just thinking about the "Four Treasures of the Study", but passing the imperial examinations was a matter of honor for the family, and if one could get a government position, it would be a real relief for their ancestors.

As for the famous Xuan paper, it is the royal family among papers, tough but moist, shiny but not slippery, white and dense, pure in texture, not damaged by rubbing or folding, and strong in wetting ink. Ordinary people can hardly see it, it is famous but they cannot afford it.

[The Song and Yuan dynasties were a prosperous period for China's papermaking industry.

The use and production of hemp paper no longer dominates, while bamboo paper becomes a newly emerging paper type, taking an advantageous position over traditional leather paper.

During the Song and Yuan dynasties, when social economy, science and culture developed greatly, the consumption of paper was even greater.

In the Song Dynasty, the belief of studying hard to become an official was deeply rooted in people's hearts, and the quality and technology of paper also made breakthroughs.

In addition, the Song Dynasty began to reuse paper. Waste paper was mixed with new materials to make pulp, producing mixed pulp paper that saved materials, time, and had quick effects.

The application of paper medicine is also an important invention of papermaking in the Song Dynasty. Paper medicine can disperse the fibers in the pulp and prevent the fibers from sticking to each other, making it easier to separate or peel the paper.

Very good, one of the few that did not criticize the Song Dynasty.

Zhao Kuangyin was repeatedly described by Tianmu as a "big loser" and a "big coward", and he felt that this ancestor was almost sinking into the dust.

The poets of the Song Dynasty were very happy when Tianmu praised their prosperous culture. How could there be only shortcomings to be said about the Song Dynasty, which was full of talented people? Passing imperial examinations was the goal they wanted to achieve by studying every day.

Zhao Kuangyin was still penniless now. He looked up at the sky and talked about the prosperity of his Song Dynasty. Thinking of the emperors who came after him giving him annual tributes, he felt painful!

Thinking that the ones behind him are the second son's descendants, let them develop the economy. They are eating the food of the Song Dynasty anyway, so they have to make some contribution.

Zhao Er: Just ignore me, woooooo...

Ming and Qing Dynasties

The Ming Dynasty was a period when there were many types of paper, and almost all famous papers could be imitated.

There are five main steps in papermaking in the Ming Dynasty.

The papermaking method is the paper-copying method which was widely used in ancient China and has a relatively fast manufacturing speed.

The steps are as follows: cutting bamboo and floating in the pond, lighting the bamboo shoots with sufficient fire, washing the materials into curtains, covering the curtains with paper and drying with full fire.

There were more than 100 varieties of paper in the Ming Dynasty, only some of which were printed.

The Ming Dynasty government also attached great importance to the papermaking industry. In the first year of Yongle (1403 AD), Emperor Chengzu ordered the construction of a large government-run papermaking factory at the site of Cuiyan Temple in Xishan, Xinjian County, Nanchang Prefecture, Jiangxi Province, and sent eunuchs to supervise the production of high-quality Chu paper for use in the imperial court.

In the same year, the "Yongle Encyclopedia" edited by Xie Jin when he was in college was written on this kind of paper.

Unfortunately, due to wars, the Yongle Encyclopedia was snatched by many countries in modern times, and most of it ended up in Japan.

It is the largest encyclopedia in the world so far, but its original copy has disappeared. 】

Yongle period

Zhu Di seemed to be frozen, but a surge of anger erupted from the bottom of his heart, making him a little shaky.

When I saw the stolen goods museum before, I learned that the Yongle Sword was stolen, and the Yongle Encyclopedia, which has not yet been completed, is also missing. This is the hard work of so many people, but it has been wasted like this.

Even if many people do not understand its value, after hearing Tianmu's words of regret, they will know that this thing is very precious and can be said to be worthy of a world name.

Ying Zheng also thought of the treasures that were lost after the invasion in the war years of later generations. Those bandits were really hateful.

But the old China was in turmoil and had no military protection, and those in power were incompetent. The powerful countries' guns and cannons were no match for them, not to mention these collections that were lost from the Central Plains.

[In the early Qing Dynasty, the paper manufacturing process was further improved and the quality of paper was also improved.

People introduced processes such as sizing, adding silt, dyeing, waxing, polishing, gold sprinkling, and printing to make paper more exquisite.
