What are the characteristics of the regular script of "Yi Qian Buddhist Niches"

Although the "Yi Qian Shrine Stele" is called a stele, it is actually carved into a cliff in the shape of a stele. On the south side of Binyang Cave in Longmen Grottoes, Luoyang, Henan today. This stele draws on the method of Han Li's broadness and European style's strictness. The knots are square and solemn, the strokes are evenly spaced, and there is a graceful and graceful beauty in between. It is a representative calligraphy work of Chu Suiliang's artistic style in the formative stage.
