Regular script in Wei and Jin Dynasties, whether in small script or tablet style, is very rigorous in structure and vivid at the same time.
To learn ancient books, it is precisely to learn Wei and Jin Dynasties. Wei and Jin Dynasties were actually a transitional period, from official script to regular script. It was not until the end of the Eastern Jin Dynasty that regular script began to form its own school, and it was not until the Tang Dynasty that it became a great instrument. In fact, the evolution of calligraphy is the gradual convenience of writing, and paper has been widely used since the Wei and Jin Dynasties. Bamboo slips are gradually eliminated and are no longer the main carrier of writing. Regular script is related to the extensive use of paper.
