What are the characteristics of Dang Yu's calligraphy?

Mr. Dang Yu's calligraphy style, like a bold and unconstrained style, is free and unrestrained. Some of his works are open and closed, and others are wrapped in iron, which is both heroic and beautiful.

In addition, in his research and creation, he is energetic, courageous and adventurous, and he has integrated the brush and ink techniques of Chinese painting into his writing skills, just like adding high and clear chords to the elegant and long rhyme of erhu, which makes his modernist calligraphy creation shine.
