Suggestiveness, not articulateness, is the ideal of all Chinese art, whether it be poetry, painting, or anything else. In poetry, what the poet intends to communicate is often not what is directly said in the poetry, but what is not said in it. According to Chinese literary tradition, in good poetry "the number of words is limited, but the ideas it suggests are limitless." So an intelligent reader of poetry reads what is outside the poem; and a good reader of books reads "what is between the lines." Such is the ideal of Chinese art, and this ideal is reflected in the way in which Chinese philosophers have expressed themselves.
