Second, what are the characteristics of Liu Gongquan's calligraphy?

It is characterized by steep knot in the middle of the plane and symmetrical stippling. Some words will be slightly tilted to the left in the knot, and the composition will be arranged by the size and thickness of the font, which looks patchy. Above the brushwork, there are more pens and vigorous fonts, giving people a sense of clank. Liu Gongquan himself is an upright man, and his regular script well explains what "books are like people".

Liu Gongquan's representative works include Mysterious Pagoda Monument, Shence Army Monument, and Small Case Diamond Sutra. Among them, the most famous one is the mysterious pagoda stone tablet, and his running script "Letters to the Imperial History of Mongolia" is also a famous post that has been passed down through the ages.
