typography

Chinese printing is the forerunner of modern human civilization, creating conditions for the widespread dissemination and exchange of knowledge.

In the early days, in order to record events and spread experience and knowledge, people created early written symbols and sought a medium to record these characters. Due to the limitations of the production methods at that time, people could only use natural objects to record written symbols. For example, carve and write words on rock walls, leaves, animal bones, stones, bark and other natural materials. Since the materials for recording texts are very expensive, only important events can be briefly recorded. Most people's experiences can only be transmitted orally, which seriously affects the development of social culture.

After the unification of writing in the Qin Dynasty, Chinese characters developed rapidly. Scholars should read official history and classics, and literate Buddhist and Taoist believers should also read Buddhist scriptures and Taoist scriptures. As a result, society's demand for books has increased significantly. The invention of paper provided society with high-quality, lightweight, and cheap writing materials, and promoted the development of books to a certain extent. The Southern and Northern Dynasties were a prosperous era of paper manuscripts. The popularity of manuscripts greatly increased the production of books and promoted the spread of culture. However, hand-copying books is time-consuming and labor-intensive, and it is easy to make mistakes and omissions. Therefore, it hinders the development of culture to a certain extent and brings undue losses to the spread of culture. During the Sui Dynasty, with the advancement of hand carving technology in engraving, printing and bark cloth printing, it gradually developed from simple and rough engraving to complex, refined and standardized engraving, which laid the foundation for the further development and improvement of hand carving technology. , creating opportunities and conditions. Under such circumstances, the wise Chinese invented printing in practice. After two stages of development: block printing and movable type printing, they presented a great gift to the development of mankind.
