From ancient times to the present, no product of an art or field of study has been able to reflect a person’s moral character and knowledge---except for calligraphy. The aura created by a person’s achievements or creations in a certain form of art or field of study often covers up his shortcomings in knowledge and character. However, calligraphy is an exception to this rule. Calligraphy is like a three-dimensional projecting mirror. The depth of one’s knowledge, the level of one’s moral character, and the strength of one’s mind are revealed through each stroke of the brush. There is no way to conceal such things. When looking at the quality of a person’s ordinary writing of Chinese characters, most people can discern the level of that person’s education. This is all the more true with respect to looking at a person’s calligraphy.
