This refers to the way to judge the artistic quality of calligraphy.
Wang Sengqian (426-485) of the Southern Dynasty and Zhang Huaiguan (dates
unknown) of the Tang Dynasty held that the primary criterion for appreciating
calligraphy is whether it features a spiritual liveliness; the concern about the
way of how to use the brush and ink is secondary. Both of them valued a
calligraphic work's spiritual verve and structural integrity and despised an
excessive obsession with superficial decorum and practical usefulness. This
preference represents a major criterion for appreciating ancient Chinese
calligraphy.
In its original meaning, dao (道) is the way or path taken by people. It has three extended meanings: 1) the general laws followed by things in different spheres, e.g. the natural order by which the sun, moon and stars move is called the way of heaven; the rules that govern human activities are the way of man; 2) the universal patterns followed by all things and beings; and 3) the original source or ontological existence of things, which transcends form and constitutes the basis for the birth and existence of all things, and for the activities of human beings. In their respective discussions of Dao, Confucianism, Daoism, and Buddhism imbue it with very different connotations. While benevolence, righteousness, social norms, and music education form the basic content of the Confucian Dao, the Buddhist and Daoist Dao tends to emphasize kong (空 emptiness) and wu (无 void).
This refers to the momentum, charm, and vitality in paintings as well as in calligraphic and literary works which together create artistic appeals. The term was first used to refer only to painting, meaning that the proper use of ink and the painting brush could vividly present natural landscape, make the painting flow with vitality, and enable viewers to appreciate its underlying allure. Later, the term was extended to cover poetry, essay, calligraphy and other literary creations. Artistic appeal, which is similar in meaning to such terms as artistic charm and literary charm, is an aesthetic appreciation gained through experiences and feelings. Expressed in a work of art, artistic appeal reflects an author’s unique approach to art and inspiration, something that he is born with rather than acquired.
