Cao Quanbei, as a representative work of mature official script in the Eastern Han Dynasty, has a high position in the minds of scholars and calligraphy critics in past dynasties. In Qing Dynasty, Sun Chengze praised him as a "treasure in Han stone" and "elegant and graceful, which reflected before and after the ceremony monument". Wan Jingping Qi said: "Beautiful flying, no binding, no rushing, is also a wonderful product." On the other hand, Mr. Kang Youwei of Nanhai thinks that he and Confucius tablet are "one family" and "both win from the wind". Xu Shujun said in "Inscription and Postscript of Bao Yazhai" that his calligraphy of "Yin Bei" is "interesting and worth enjoying". From the previous comments, we can see that the most striking aesthetic features of Cao Quanbei are elegance and quietness. Compared with the rough Han stele of his contemporaries, if a gentleman with graceful demeanor has a high level of self-cultivation, his personality is neither violent nor violent, fair and peaceful, which conforms to the norms and floats away, in stark contrast to the style of the inscription that pursues truth and simplicity.
