Although there was paper in Cai Lun before, this does not detract from Cai Lun's great achievements as a major reformer and inventor who perfected the invention of papermaking. It was Cai Lun's invention that made paper enter the practical stage and spread quickly and widely, which provided a cheap and easily available substrate for improving printing and promoting its development. Cai Lun's achievements and his brilliant image as the inventor of the great invention of perfecting papermaking are undeniable. The invention and improvement of the pen made China's writing develop towards simplification, neatness, standardization and easy engraving and copying. The invention, development and application of fabric, paper and ink provide essential printing and transfer materials for printing. The continuous improvement and combination of embossing and rubbing technology based on hand engraving and transfer printing technology and fabric printing technology laid a technical foundation for the invention of printing; Social progress and the development of cultural undertakings have created social environment and objective requirements for the invention of printing. The possession and combination of these four made the invention of printing a historical necessity, and it began to be widely used in Sui and Tang Dynasties.
