The stone carvings on Mount Tai are very valuable. This stone is the earliest existing stone carving in Mount Tai, and is known as the first stone carving in the world. Because of its mellow seal method and rich spine, it is called "Lisi Small Seal" or "Jade Seal Seal". Li Si's Xiao Zhuan not only plays a connecting role in the style of calligraphy, but also plays a connecting role in the charm of calligraphy, which has a great influence on the seal, line, truth and grass of later generations. Liu song-gang's preface says: "Li Xiao-si's biography has been learned from ancient times to modern times." Yuan Haojing's poem "Praising Mount Tai for Carving Stones" said: "The fist is as straight as a hairpin, and the Qutie grinds jade and beauty. The Millennium is thin and strong, and it is more stupid to look back at fat people. " "Dai's" says: "Although Qin has no way, his calligraphy is chinese odyssey." In Song Dynasty, Siren's Notes on Mount Tai said: "Fu Lisi's Xiao Zhuan is the eighth ancestor, and its injustice is insufficient, but the tablet is really valuable, which can follow the stone drum of Zhou Dynasty and be one step earlier than the stone carving of Han and Jin Dynasties." Mr. Lu Xun also spoke highly of it. He said: "Strong quality, Han and Jin inscriptions are also derived." Wang Keyu believes that Li Si's seal script Taishan stone carving is not only a treasure of China calligraphy art, but also a great contribution to the development of China's history and culture. "Without unified writing, there would be no unified culture; Without a unified culture, there will be no unified China. " Li Si's thought of "the same language" was adopted by Qin Shihuang. On the basis of Da Zhuan, it was changed to Xiao Zhuan with neat strokes, which unified the national characters and made China a unified country with unified government decrees. This shows that its value is great, and it deserves to be the first in the world.
