The invention of paper has brought the following benefits to social culture and people's lives:
1. The widespread use of paper provides a carrier for books and documents, thus promoting the use of books and documents. The rapid growth and spread of science and culture further promoted the development and prosperity of the art of calligraphy and the changes in Chinese character fonts.
2. Use a large sheet of paper that is white, smooth and flexible to receive ink to change the defects of the bamboo slips. The reason why outstanding calligraphers like Wang Xizhi and Wang Xianzhi appeared in the Jin Dynasty was that the widespread use of paper was a factor that cannot be ignored.
3. After the Jin Dynasty, the fonts transitioned from Han Li to Kai Li, until the current regular script was formed. Cursive script also developed as a result, and the changes in Chinese character fonts were also caused by the use of paper.
