After the efforts and expansion of many calligraphers in Wei and Jin Dynasties, and the integration and innovation of Wang Xizhi and Wang Xianzhi, cursive and running scripts began to be displayed in new ways and gradually finalized. Because the two kings and their sons emphasized the use of pen, the pen gesture continued, the structure was rich in changes, the lines were smooth, and they had great charm, thus getting rid of Cao Zhang's waves and the rigidity of writing procedures, making writing more free and interesting. For more than 1000 years, cursive script, with its vertical and horizontal posture, ups and downs, elegance and charm, has become a widely used writing form for later calligraphers. It can be said that the two kings and their sons initiated the great beginning of expressing emotion in books and really raised calligraphy to an artistic level.
Because of getting rid of the stagnant writing procedure since the previous generation, it was upgraded to graceful and elegant brushwork, which made it simple and free, elegant and smart, with outstanding charm, so the new style was widely accepted by scholars and began to prevail. Today, we can only see a few lines of Wei and Jin notes and pieces of paper. Although they are all greetings and stories, they are all fascinating, charming or charming and impressive. Therefore, the popularity of cursive script in the Eastern Jin Dynasty is attributed to the two kings and their father and son, and their contribution in the history of calligraphy is immeasurable.
