What is the origin of Fu Shan's calligraphy?

Regarding the origin of Fu Shan's calligraphy, he once said, "I was eight or nine years old in Yuanchang, and I was different. Juvenile dragons, such as Huang Ting, Cao E, Yue Yilun, Ode to the East, Thirteen Lines of Luoshen and Theory of Breaking Evil, abound, but none of them are the same. Finally, the Lugong Temple is slightly fragmented, dating back to "competing for seats", which is quite similar. Then I went to Lanting. Although I don't know what the Taoist priest looks like, I gradually want to know the general meaning of this skill. " (Fu Shan's Family Instructions) In this way, Fu Shan's nature is heroic, and it is difficult to get into strict statutes. It can be said that his grasp of tradition is far less profound than that of Wang Duo. He only mastered the general rules of calligraphy techniques, gave up the dependence on tradition, and created by his own will, forming his own face.
