Which calligraphy master's unique skill is the technique of "even dry pen"?

Different from Yu Youren's calligraphy style, Li Zhimin not only took the lead in putting forward this proposition, but also consciously explored it. He naturally embedded Fang Bi, a hero of the North Monument, and Kai Yuan Pen into the creation of Weeds, making it harmonious, round and Fiona Fang, enriching the form and style of contemporary cursive script. At the same time, on the basis of absorbing the essence of previous calligraphers, he creatively developed the technique of "Lian Gan Bi" and pushed it to the highest level. His dry pen is not scattered, continuous and weak in the constant rotation of the center, and everyone rarely touches it in the past dynasties. It can be described as Mr. Li's "stunt", which deserves to be highlighted in the history of contemporary calligraphy. Li Zhimin also left a large number of manuscripts such as letters, notes and handouts handed down from generation to generation. These different forms of letters are mostly written in weeds, which are natural and free, and are rare and precious calligraphy products.
