This volume makes Huai Su's thin, tenacious and swift pen thin, hard and changeable, makes "Huai Su's self-narration" more compact and dense, makes the blank space appear more, and swings from left to right, forming the image of clouds rolling and clouds blooming. This volume mostly uses "one book", and many lines do not change pens. The voluminous volume profoundly explains the heroic and ethereal artistic conception in Li Bai's poems. Su Dongpo's "not practicing the ancients" is consistent with Huang Tingjian's aim of "approaching the ancients", that is, it is not similar to the ancients, but in line with the spirit of the ancients' art. Huang Tingjian saw that cursive script changed after "self-report", not because Su Shunqin and others followed suit to describe Huai Su, but because he was "sui generis".
