The printing exhibition was one of the four major inventions in China and was known to all in this layer. As for the invention and development of books binding and casting, few people pay attention to it and study it. After all, this is a pity in the study of printing history. The invention of the bookbinding technology was far ahead of the invention of printing for about two thousand years. The oldest existing script in our country is "Oracle." From the archaeological discovery of Oracle, it is proven that as early as 3,300 years ago, the Chinese language had a sound foundation. With the evolution of hieroglyphic and morphological texts, the most primitive books have begun to appear, namely, the earliest “turtlebone book†has appeared. The book of tortoise bone was produced in the Shang Dynasty era from 1600 BC to 1100 BC. Its use lasted until the early Western Zhou Dynasty, ie the Wu, Cheng and Kang eras. The use period was about 800 years. The materials used to make the book are bone and bone. The tortoise shell is called "A", and the abdomen (bone) A is the main, and the back (bone) A is supplemented. Because the abdomen is flat and light in color, it is easy to inscribe letters, and the backbone is uneven and dark, making it difficult to write text. The scapula of cattle and sheep is called "bone", and there are very few animal ribs used as the material of the book. After writing these materials with text (usually hieroglyphs), the platoons were affixed to a booklet, which was an early binding form—the turtle bone book was installed. This method of binding and the materials used are very complicated and cumbersome now. When writing books, you need to slaughter cattle and sheep and catch turtles, and then use a knife to write one word. But the original invention process was difficult and long for our ancestors. In the Western Zhou Dynasty, people summarized the book of tortoise shells as: "After being stacked and made into a series, the traditional ones are used for leather (cutting) and they are collected for easy inspection." It can be seen that the invention of the book of the Turtle Book brought great benefits to the people at that time. It was verified that in the 1976 artifacts unearthed in Anyang, Henan Province, several turtle shells and shoulder blades were discovered. One of the more complete turtle pieces can also see the text above and the joining material used. There is a piece of the lower left corner that also clearly engraves the word “=†(6). Then one, two, three, four, and five volumes can be inferred. There is a gap in the upper right of this turtle piece, and there is a rotten animal thong beside the gap. This shows that the gap is a hole (broken), used to cross-link the oracle bone, and the puncture-binding material used is a strip cut from animal skin. With the development of society and the progress of mankind, people gradually feel that the use of tortoise shells and animal bones for recording and writing not only lacks materials but also makes them difficult to produce, and their use and storage are inconvenient. By the Spring and Autumn Period and the Warring States period of 770-221 BC, social production had made great progress, and people's demands for cultural science began to have a new understanding. The bulky tortoise book, because it can no longer meet the requirements of social and cultural development, people gradually use bamboo as a substitute for bone material to record text. However, recording text with bamboo strips has gone through a process from carving a knife to writing with a pen and ink. The room written on the bamboo strips is called the room. A few of them are written on the wooden planks and they are called wood slips. The ones written on the wooden planks are called woodblocks, and they are collectively referred to as Jane. "Jane" is like the title of "page" now. Bamboo slips are mainly used for large texts. They are mainly used for letterheads, notices and the like. Simply bundling leather slivers or vines and silk into a bundle, that is, a "strategy." The wording comes from "" and later it turns into "book." The use of the word strategy at the time was a reference to a strategy book. Later, especially after the publication of "The Art of War", the word strategy was used mostly for "strategy," "decision making," and "policy," and was gradually separated from the use of the word "book." The method of splicing with leather or rattan is known as "Waibian", and the method of using silk sew is called "silk knitting". Just like the current thread binding and iron wire binding, it is not just the use of materials. These binding methods are recorded in the "Historical Records". Jane and ç‰ is a certain size specifications. The general length of Jane is 6, 8, and 12 inches, and the width is approximately 0.5-1 inches. In the cultural relics unearthed in Linyi, Shandong Province, a batch of military books of Sun Tzu and Sun Ting were found. They have a number of branches. Their length is about 6 inches, their width is only 0.4-0.5 inches, and their thickness is about 1.5mm. . It can be seen at that time that people are cutting their skills. When Jane is in use, each line can be written with 1-2 lines. When connecting, several lines can be used according to the length of the Jane, usually 2-3 lines, or evenly divided into leather or rattan or silk. A bunch, that is, a policy. The origin of the strategy word is "bunch" with the word "bamboo" as the "measure." Before and after the policy, there are generally 1 or 2 or 3 simple texts that are not written. The reason is that the head and the tail are easily worn out, and the effect is similar to that of the front and back sheets of books. While reading, simply put a bunch of flats and read them and save them by rolling them up. The specifications of the concrete are generally one square metre and the thickness is not limited. Mostly used for large and small texts, more specific, clear and concise text, such as letters, notices, etc. In ancient times, there were more Jane than Jane. Although there has been a lot of progress in comparing the Jane-set books with the Turtle Book, it is still very cumbersome and inconvenient. There are many such records in the ancient books. For example, after Qin Shihuang unified the world, his daily memorial was "a scaled book with Heng Shi". Qin Shi's stone is equivalent to the current 120 Jin. It can be seen that the Qin Shi Huang one day reads many documents, so there must be attendants to pull books, carry books, and bundle them. During the Eastern Han Dynasty, there was a scholar named Dongfang Shuo. He wrote to Emperor Han Guangwu. He wrote up to 3,000 bamboo slips, and Emperor Wu of Hanjiang saw "February is the best." Among the large number of ancient bamboo slips found in our country, the most complete ones are the "Sun Tzu Art of War" and "Sun Tzu's Art of War." There are literally a few thousand of these books. Their time was about the year of Emperor Wu of Han Dynasty, around 140 BC. The tortoiseshell booklet and the simple installation, especially the size, connection method, and use form of Jane's installation, all laid a good foundation for the later binding technology, such as the size and method of bookbinding for later books. , process forms, and so on, have had an important impact. Recently, a large number of earlier artifacts have been unearthed in Zhangqiu County, Shandong Province. The objects unearthed may be related to the bookbinding technique. It is hoped that the excavators and researchers will pay attention. At this point, we can say that there is no country in the world that can prove the advent of bookbinding earlier than the 16th to 11th century BC. Our country not only has physical proofs, but also has clear historical records. It can be concluded that binding and printing were first invented by our ancestors. Finally, I hope that the China Printing Association, China Printing Museum and other relevant responsible part, organize relevant personnel to conduct a more in-depth study of the invention of China's binding art, in order to enrich China's cultural treasures and promote the national light of our country.
