Pan Tianshou said in "Painting in China" that the painting in Wei and Jin Dynasties "inherited the legacy of the late Han Dynasty and followed it". The same is true of calligraphy in Wei and Jin Dynasties. During the Wei and Jin Dynasties, official script and even seal script were still used for serious inscriptions and classic writing. It also produced a number of excellent calligraphy works that mainly inherited the tradition. Judging from the development of China's calligraphy, Wei and Jin Dynasties is an important historical stage to complete the evolution of China's calligraphy, and it is a perfect generation of seal, official, truth, line and grass. So far, Han Li has finalized the basic form of square Chinese characters. The emergence, development and maturity of official script gave birth to regular script (now also called regular script), while running script and cursive script sprouted almost at the same time as official script. Authentic works, running script and cursive script, three important styles of China's calligraphy, were shaped in Wei and Jin Dynasties. This moderns in the history of calligraphy has created two outstanding calligraphers in Li Zhuo, Zhong You and Wang Xizhi. They turned a new page in the history of calligraphy in China, and set an example of the beauty of real calligraphy, running script and cursive script. Throughout the Wei and Jin dynasties, famous artists came forth in large numbers, with rich relics and salty bodies, all of which were perfect. Famous calligraphers except Zhong Wang, Wei Youwei and Suo Jing are all famous for cursive script; Wu has a statue of an emperor, and his is "calm and happy"; In the Western Jin Dynasty, Lu Ji and Ping Fu Tie were handed down from generation to generation. In the Eastern Jin Dynasty, Wang Xianzhi of the Wangs studied French and expanded it with his pen. Mi Fei called him "a pen like fire, but it is endless. If it is careless, it is called a book". As for the gold edition of The Three Kingdoms unearthed in Xinjiang, it is a figure with a strong sense of brushwork in official script after the transition from official script to official script, which is very interesting and provides excellent material for studying China's calligraphy pen.
