Brief introduction of nine potentials

"Nine Potential" is also called "Nine Potential Eight-character Tactics", written by Cai Yong in the Eastern Han Dynasty. Chen Si's Book Garden in the Song Dynasty has expounded the law of calligraphy, which has been preserved to this day and occupies an important position in the history of China's calligraphy theory. Cai Yong mainly put forward three aesthetic concepts about calligraphy lines in Nine Potential, namely "strength", "potential" and "hiding". "Force" is the core of Cai Yong's calligraphy aesthetic thought. It is emphasized that "force" is the basis of writing, writing and typesetting, and "force" can make fonts have the beauty of "skin beauty". "potential" is a directional "force", which is often used to refer to a certain direction in the creative process, indicating that "the potential is deep and unstoppable" "Zang" comes from the philosophical thought of "a gentleman hides utensils", which emphasizes that calligraphy creation needs to be calm and implicit. Specifically, it is necessary to "hide the head and protect the tail" and highlight the tension of calligraphy lines. These calligraphy thoughts have made important contributions to exploring the aesthetic significance of calligraphy lines.
