Liu's body is balanced, thin and hard, chasing Weibei steadily, with smooth and beautiful stippling, thick bones and tight body. "Books are expensive, thin and hard, and the spirit is clear." Compared with his face, his regular script is slightly flat and thin, so it is called "Yan Gu".
Calligraphy features: vigorous and powerful, rigorous and meticulous. As far as the characteristics of Chinese characters are concerned, they are famous for their thinness and strength. The regular script written is beautiful and strong, and the running script and regular script are the most exquisite. But also because of the uniqueness of his works.
Clear pronunciation and mellow voice, thin and hard, firmly follow Weibei. The stippling is crisp and beautiful, strong and rigorous, and it is known as "Yan Gu". The regular script of "the book is expensive, thin and hard, and the spirit is clear" is slightly thinner and harder than the surface.
