Printing is arguably one of the four most outstanding inventions of the Han Chinese in ancient China, and one of the four great inventions that have had a progressive effect on all other civilizations in the world.

Printing originated from Taoist engraving printing, it was active in the engraving printing of the Sui Dynasty, developed and perfected by Bi Sheng in the era of Song Renzong, and finally produced movable type printing, and from the west, the Europeans were horrified to call the Mongolian whip of God to Europe, because it was because of Bi Sheng that movable type printing appeared, so later generations called Bi Sheng the ancestor of printing.

Chinese printing can be said to be the forerunner of modern and even modern human civilization, and its emergence has created conditions for the wide dissemination and exchange of knowledge of various ethnic groups.

The printing technology invented by China has been transmitted to Korea, Japan, Central Asia, West Asia and Europe, so to speak, but the printing technology of the time, as long as the entire known civilization world, has the shadow of the printing technology that has been passed down from China.

The movable type printing technology invented by Bi Sheng can be said to be a great technological revolution in the history of printing, the method of movable type printing is to first make a single word of the yang text reverse text mold, and then according to the manuscript to pick out the single word, arrange it in the word plate, ink printing, after printing, and then remove the word mold, leave it for the next typesetting to be used again, compared with the original engraving printing, it can be said to be much more advanced.

Before the invention of printing in China, the dissemination of culture mainly relied on hand-copied books, but hand-copied books were not only time-consuming and troublesome, but also easy to copy mistakes and omissions, which not only hindered the development of culture, but also brought undue losses to the spread of culture.

Seals and stone carvings provided direct empirical inspiration to printing, and the method of using paper to ink on stone tablets directly pointed out the direction for engraving printing.

In the early days, the printing technology of ancient China went through two stages of development, engraving printing and movable type printing, and presented a generous gift to the development of various nations in the whole world.

Compared with the earliest seals and stone carvings, the characteristics of printing are not only convenient and flexible, but also time-saving and labor-saving, which is a breakthrough in ancient printing.

Chinese printing has a long history and spread widely, and it can be said to be an important component of Han culture along with the other four major inventions. It sprouted with the birth of Han culture and evolved with the development of Han culture.

If we count from its source, it has gone through four historical periods of source, ancient, modern and contemporary, with a development process of more than 5,000 years.

The ancestors of the early Chinese nation recorded events and disseminated experience and knowledge. He created early written symbols and sought a medium to record them.

Due to the limitations of the means of production at that time, the ancestors of China could only use natural objects to record words and symbols, cover the sun, and engrave and write words on natural materials such as rock walls, leaves, animal bones, stones, and bark.

This is because the materials used to record the text are very expensive. Therefore, important events can only be briefly recorded, and the experience of most people can only be transmitted orally, which strictly influenced the development of society and culture until the invention of printing.

Not only that, the invention of printing not only gave the evolution of all nations in the world a pair of wings to take off, but also relied on the strong combination of printing and papermaking in China, and finally disintegrated the more than 1,000-year-long period of family economics. made the once widely spread saying that the top grade has no cold door, and the lower grade has no warriors, and finally became a swan song.

Cao Cao, who has the memory of later generations, of course, could not let go of this big killer, as early as the beginning, he ordered those craftsmen who were lifted up by themselves, and began to study its printing technology with all their might. This Chinese nation is the greatest, the world's greatest, the greatest invention. Finally, in August of the fifth year of Jian'an, it was completely presented.

Movable type printing of printing can be said to have gone through several stages, namely letterpress printing, lithography, gravure printing, stencil printing, flexographic printing, although Cao Cao has the memory of later generations, but he does not speak of God. Again, there are no golden fingers that are clearly beyond reality, and even with his construction, a few years later, the printing technology invented by these craftsmen is still in the first stage, that is, letterpress printing.

Letterpress printing has the longest and most popular history, and the convex parts of the layout images and text accept ink, and the recessed parts do not accept ink, and the ink is printed on the paper when the plate is pressed against the paper.

Its printing plates mainly include movable type plates, lead plates, zinc plates, copper plates, etc., although it is the first stage of movable type printing, but Cao Cao is still very satisfied.

Not to mention that after this, those ideas in his mind can begin to be formed and implemented, and even in his previous life, there are still some books, periodicals, bills, envelopes, business cards, etc., which are still using letterpress printing; Some of the things that want special processing, such as hot stamping, silver, embossing, etc., are also used in letterpress printing under the general circumstances, so it can be seen that although it is the first stage of movable type printing, its practicability and success are unknown.

"Okay, okay, you and other fifteen people, from today, take off the people's body, and Gu officially grant you the position of a fifth-level craftsman equivalent to the position of a five-grade official, I hope that you can make persistent efforts in the future, continue to invent things that shock the world, and the things you invent today will be left in history, and your name will be known to future generations!"

"Thank you, long live you!"

The fifteen craftsmen present heard Cao Cao's reward or the meaning of Cao Cao's words to leave their names in history, and they all knelt on the ground with joy, shouting long live. The appearance of the position of fifth-level craftsman obviously has no other explanation except for Cao Cao, the initiator.

In order to better manage, but also to stimulate the fighting spirit of those craftsmen, Cao Cao distributed the craftsman rank a long time ago, according to the idea of nine extremes in the minds of the ancients, Cao Cao's division of the craftsman grade came from this.

The lowest-level craftsman is the one who has no quality, such a craftsman, Cao Cao divides it into apprentices, as the name suggests, such a craftsman is only an apprentice and not a craftsman who can take charge of manufacturing and even inventing on his own.

Above the apprentice is the ninth level and the deputy ninth level craftsman, this kind of craftsman who has been awarded the grade corresponds to the official from the ninth grade, the eighth level corresponds to the eighth grade, the seventh level corresponds to the seventh grade, and so on, the highest level is the first level, and in order to reflect the status of the first-level craftsman, and at the same time to inspire those craftsmen, Cao Cao added another title to the craftsman at this level, calling him a master.

The development and increasing sophistication of Cao Jun's weapons, it can be said that Cao Cao's policy has played a decisive role, the Han people have never lacked the creativity and creativity of invention, what is lacking is only the king who saw and used it, and Cao Cao, a person from later generations, can know that the China in this time and space, its civilization from the blooming brilliance, will inevitably be more brilliant.
