Liang Wudi Xiao Yan praised his words as "powerful and dangerous". A vigorous place is like a sudden wind, and the stork flies first; Dangerous places are like solitary pines in snow-capped mountains and dangerous rocks in glaciers. Huang Valley also praised his calligraphy as "short and long, sincere and unattainable". Some people compare Suo Jing's ci with Zhang Zhi's ci, saying: "Being excellent is not as good as Zhang Zhi;" "Wonderful, not as good as Zhang." The calligraphy of the two masters is different.
