The font of the stone drum inscriptions is based on the bronze inscriptions of the Western Zhou Dynasty and the small seal scripts of the Qin Dynasty. From the calligraphy point of view, the stone drum inscriptions are inherited from the "Qin Gong Gui" (a bronze ware in the mid-Spring and Autumn Period, with ten lines of inscriptions on the cover and five lines on the vessel. 121 words in total) His calligraphy is the forerunner of Shigu and Qin Zhuan, and his writing is square and generous. Where the pen is folded horizontally and vertically, a square is contained within a circle. The vertical painting at the turning point is retracted and gradually stretches downward when going downward. Its momentum is rugged and elegant, with the Qin Dynasty's powerful hegemony. However, it tends to be more square and rich. The beginning and end of the strokes are all sharp, round and vigorous, the structure is lengthened and shortened, and it is well-proportioned and moderate. The ancient majestic beauty is the best in ancient and modern times. Shiguwen is the collection of large seal scripts and the first of small seal scripts. It plays a role in the history of calligraphy as a link between the past and the future. It is a transitional font that evolves from large seal script to small seal script but has not yet been finalized. Shiguwen was regarded by calligraphers of all dynasties as an important model for the practice of seal script.
