Zibo's calligraphy refers to which three kings?

Wang, Wang Fayan.

Wang is good at running script, his works are sharp and clear, and his pen is refreshing. His regular script is slightly close to the North Monument, with warm words and steady strokes, although every word of the thousand-character macro is slack.

Wang Yanshan is good at official script, which is simplified to fine print. Its official script was spread in many divisions and participated in seal script, each with its own interests.

Wang Fayan is best at cursive writing, and his works are in sharp contrast, scattered and rhythmic. He is known as the three kings of calligraphy in Zibo.
