From Wikipedia:
"Asian aesthetic writing is generally consistent in stating the goal of ink and wash painting is not simply to reproduce the appearance of the subject, but to capture its spirit. To paint a horse, the ink wash painting artist must understand its temperament better than its muscles and bones. To paint a flower, there is no need to perfectly match its petals and colors, but it is essential to convey its liveliness and fragrance. East Asian ink wash painting may be regarded as a form of expressionistic art that captures the unseen."
