Li Si represents the calligraphy characteristics of the inscriptions.

It can be seen from "Carving Stone on Yishan Mountain" that Lisi's calligraphy is vigorous and smooth, with rounded lines, well-balanced structure and even stippling thickness, which has both the beauty of patterns and the tendency of flying. The superb skill of calligraphy conceals the antecedents and disperses the later sages, making it difficult for all people who write biographies to enter their territory and become good copies for future generations.

The brushwork of this tablet is simple and neat, hidden from people, round and round, with all corners in an arc shape and no pen outside. The symmetry and balance of the knot, as well as the stress on seeking change in symmetry, have a decorative beauty like a pattern, which conforms to the golden section law. Rules and regulations are orderly and rhythmic.

Yishan stone carving is also called Qin Zhuan stone tablet, Yishan stone tablet and Yishan stone tablet in Yuan Dynasty. Originally located in the lobby of Zouxian county government, it moved to Gongmen of Mengmiao in the early years of the Republic of China, and 1973 moved to Qimiao for preservation.
