"People who have read Su Shi should know that his advantage is not that he can use allusions such as Jade House and Hai Yin, but that he can use common things such as Niuya and Niulan to make good poems. What is good in his regular poems is only poems written in the style of speech. "

Lv Simian (1884- 1957)

"Sansu's essays are roughly the same, but they also have their own characteristics: the pen is strong and the old spring is the heaviest. However, Lao Quan is good at telling the truth and is always complacent about his power, but his words are useless ... and Dongpo can really see the truth of things. Therefore, its ice and snow cleverness is beyond the reach of Laoquan. It is especially wonderful in the pen. "

Qian Zhongshu (19 10- 1998)

"When he (Su Shi) criticized Wu Daozi, he once said:' Innovation lies in statutes, and mystery lies outside the uninhibited.' Judging from the poetic comments scattered in his works, these two sentences may be applied to himself casually to summarize his poetic theory and practice. The' unruly' in the last sentence should be thought-provoking, not drunken rampage. The definition of "unruly" in the previous sentence, in the words that Su Shi can understand, is "do whatever you want and don't overstep the rules"; In modern terms, freedom is based on the understanding of regularity, and creativity has full freedom under the permission of artistic laws. This is exactly what Su Shi has repeatedly stated. The composition should be as free and lively as' flowing water' or' flowing clear water', but at the same time, it should be very cautious to' do what should be done and what cannot be stopped'. After Li Bai, no one in ancient times could match Su Shi's boldness. "
