So I give a popular definition of calligraphy: "Calligraphy is a standard brush character." Of course, it can also be said that "calligraphy is artistic calligraphy", and the art of calligraphy is to standardize the writing of brush, that is, to write brush according to the rules of calligraphy.
Any art has something in common, and this similarity lies in the law of art, and following the law of calligraphy is the art of calligraphy; Following the law of painting is the art of painting; Following the law of sculpture is the art of sculpture; Following the laws of architecture is the art of architecture; Following the tailor's rule is the art of tailoring.
The rules for writing Chinese characters are how to start writing, how to write, how to bend and hook, how to write in sequence, and how to structure. These are all knowledge. Calligraphers must also be Chinese linguists and have a thorough study of thousands of Chinese characters. Only when he writes down every word can he become a calligrapher. A calligrapher, at the same time, must be a writer in China, proficient in classical literature and classical poetry. He must be able to write (write according to the rules) and read (know and understand) in order to complete a calligraphy work.
