Lishu has sixteen lines of steles and thirty-six words, and seventeen lines of steles; There are three columns and four rows on the left side of the monument; There are four columns and four rows on the right side of the monument. Ritual tablet is the most typical representative of the subordinate relationship of Han tablet. Calligraphy style is thin, vigorous and dignified, with broad structure and vigorous strokes, which occupies an important position in the history of calligraphy in China and has far-reaching influence. Guo Zongchang's "Stone Story" commented on this monument: "The beauty of its calligraphy and painting is neither a pen nor a hand, and it is quaint and unpretentious. If it's providential, it's artificial. The so-called "the stars flow and electricity turn, and the fiber is over-valued" is not enough to describe. The monuments of the Han Dynasty are all like life, but this monument is as unique as the Hehan, and it is impossible to meet. " Wang Qing commented on this tablet cloud: "No beauty is unprepared. I think it's clear and super, but it's vigorous. I think it is vigorous, but it is restrained. " No one has been so wonderful since we parted. Fang Shuo's Inscription and Postscript on Stone Paintings and Calligraphy in the Pillow Classics Hall in Qing Dynasty says: "The beauty of building this monument lies not in neatness, but in change, not in sufficient momentum, but in good brushwork. Although there are many excellent Han steles, taking this as a starting point, the beauty can be copied, the founder can also copy, the old can copy, and the ups and downs can't copy. The positive change of Caledonian law is that the text, yin and edge of this monument have been exhausted, so there is no need to refer to them one by one.
