Say "Yan Jin" first. Yan Zhenqing's calligraphy, vigorous and powerful, is called "Yan Ti" by the world. Its most obvious colors are "swallow-tail of silkworm head" and "horizontal light and vertical weight"
Say "six valleys" for the second time. Liu Gongquan's calligraphy, a beginner of Wang Xizhi, later learned from Yan Zhenqing, and adopted the strengths of calligraphers of past dynasties, melting into a whole, that is, "Liu Ti". Liu Ti is called "Liu Gu" because of its rigorous shelf and upright character.
