Liu Gongquan's regular script is vigorous, steady but not vulgar, risky but not strange, old but not withered, moist but not fat, harmonious and charming. The brush strokes are even, hard and thin, with exposed edges and corners, rich and diverse, so as to avoid monotonous repetition. Most horizontal paintings are round, rigid, clear, short, thick, slender and handsome. Vertical painting is vigorous, stiff, slender, concise and firm, sharp, heavy and slightly short, kicked up and cleaned with a pen.
