The "shape" of calligraphy art can not be separated from "potential". Military strategists emphasize power, and calligraphy emphasizes brushwork. The predecessors' comments on books are all about the situation, so there is a theory that "writing a book must predict the situation". In pen and ink skills, potential often represents the "ribs", "veins" and "qi" of words. If a calligraphy work is word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word, word for word.
Some excellent works in ancient times are magnificent, unrestrained and unstoppable; Some are agitated and depressed, showing a state of flying spirits; Some are quiet and dense; Some are dripping and hearty; Some stretch vertically and horizontally; Some people are reunited in spirit. Although the techniques are different, they are all unconstrained and unconstrained, the words are straightened out, the heart and hand meet, and they are manipulated freely, giving people an artistic feeling of blood connection and success. Works lacking motivation are dull, dull and have no commercial flavor. The beauty of situation is a spiritual realm that runs through the whole calligraphy. Knowing the situation is an important criterion for appreciating and evaluating calligraphy.
