What is Wu Shuo's background?

Wu Shuo is not only a pen maker, but also a calligrapher. His calligraphy went deep into the hall of Huang Tingjian, thanks to Zhong You, who was particularly good at writing miscellaneous books and gossamer grass. His inscriptions and plaques are very important to the world, and the book handed down from generation to generation is Wang Anshi's Su Shi's poetry anthology.
