Who is the calligraphy master who initiated the calligraphy style of "attracting monuments into the grass"?

As a calligrapher with profound academic foundation and artistic creativity, Li Zhimin, a senior professor in Peking University, deeply realized this development trend as early as 1970s and 1980s. On the basis of learning from the experience of previous calligraphers, he took the lead in clearly putting forward the proposition of "attracting monuments into the grass" and made pioneering attempts and explorations. Weibei is not only good at writing, but also first-class in wild grass. He and Shen are called "two masters in the history of calligraphy in Peking University" and "Nanlin Beimei". As early as the 1970s and 1980s, he deeply understood this development trend. On the basis of learning from the experience of Zhao, Yu Youren and other predecessors, he not only took the lead in clearly putting forward the proposition of "painting a monument into the grass", but also consciously explored it, making it a leading figure in the North Monument.
