What really shows Sun Dayu is his broad mind through the great realm of painting and calligraphy. Art is character. I sincerely admire Mr. Sun Dayu's works, but what I admire more is his personality. The ancients said: learning books lies in the law, but its beauty lies in people. Method, can spread to all, and wonderful, must be its chest. Sun Dayu's success in painting and calligraphy lies in his uniqueness and self-shaping in a sense. He is heroic, open-minded, not greedy for wealth and fashion, and drinks heartily when he meets his confidant; Friends get together, chat and entertain themselves. He speaks bravely, and when his friends encounter any difficulties, he will always have a personality power to make progress. Sun Dayu, a person who values affection and righteousness, a noble and lovely person, and a person who "takes books as friends, poems as friends, and has a flamboyant personality". Yan Fang is a true sage, and Lingyun has a pen to fight the sky; Poetry, wine and luxury come from Qilu, and Fengshen surpasses books.
"Bald pens are also stupid and crazy." Sun Dayu's calligraphy gives people a feeling of "unstoppable deep stone" and "pen as the body and ink as the character". Dayu's poems give people a feeling of "broad-minded, passionate" and "artistic conception in today's world". His achievements mainly depend on his strong ability to understand and digest tradition, structural deformation and formal composition. In particular, the list characters that ordinary people dare not ask are integrated with measurement, neutrality, smoothness and reversal; Combining dry, wet, thick and light brushwork in one furnace, the works can give people a strong visual impact and shock. Zheng, a famous painter, rated his calligraphy as "vigorous, practical and ambitious", while Guo, a famous calligrapher, summed up his character and calligraphy with the words "gentleman's style and integrity".
