Wang Fuan's Shuo Wen Bu Tou is one of his typical representative works. Its pen is pure and single, and the three-dimensional effect of starting, starting, closing and turning has been rounded and profound. The structure is balanced, accurate and full of charm, and the seal cutting does not break the rules, which reflects his maturity and ultimate performance in grasping the small seal cutting. Based on this, we choose words for specific technical analysis and guidance, in order to have a preliminary understanding of Xiao Zhuan. Beginners can not only master the structure and pen of Xiao Zhuan, but also lay a solid foundation in understanding.
