The history of development
At present, Chinese people are able to understand the status of the slave period before 3000 years, know the situation of warring states period that all ideas compete with each other through showing their prosperity before two thousand years, read the rhyme, all Chinese poems depend on the ancient books.
The earliest books can be found in Shang dynasty, which is made of the bamboo and wood. Owing to lacking of the written material before the Paper and Printing was invented. These common and available raw materials were cut into narrow pieces, with brush to write on. We call the bamboo pieces as “bamboo slip”and the wood pieces as “wooden slip”, both are called as” slips”.We usually take down only one line on it and use a knife to scrape to rewrite if we make mistakes. So we called deleting and correcting article as “revision” in ancient times, which word is still used today. Now the sizes of books are vary, the length of ancient slips is also different, the longest one is three feet, the shortest one is five inches. Writing a book require plenty of slips, weave these slips into “volume”. Most of the “volume” are weaved with hemp rope, the silk rope can be also used (called “Silk Braiding”) or leather (called “Leather Braiding”).The “The Three Broken Leather Braiding” mentioned in ancient books means that the famous ideologist Confucius who often reads the book<< The book of Changes >> and makes the leather broken three times. The number of braiding in a book depends on the length of slips. Generally, we use two or three braiding, sometimes four or five braidings can be used to make up a book. Now we often describe the number of books as “volume”, which actually is a pictographic character, just like the shape of weaving a slips with rope.
