Who are the "two kings" in the history of China's calligraphy and painting?

Ancient major calligraphers:

1, Wang Xizhi

2. Wang Xianzhi (344-386)

Wang Xianzhi's calligraphy collection and appraisal can be compared with Wang Xizhi's. Father and son have their own merits in calligraphy. Xi showed his real behavior, while he devoted himself to cursive writing. The most innovative and valuable thing about Two Kings is its elegant cursive script. Wang Xianzhi was not embarrassed by his father, so he was innovative, handsome and brave, and set up his own family, which made people sit up and take notice. Unfortunately, God was jealous of his talent and he died prematurely at the age of 42.

Wang Xianzhi has Cao Zhang's "Post on July 2nd", and its lower case is represented by "Thirteen Lines of Luo Shen Fu", which is extended with a pen, with a well-proportioned and neat structure, like a good family, and a charming and graceful posture. His running script is duck head pill post.
