Use long contrast to form a snow scene.

In "Scenery of Jiao Mo", Pan Tianshou used the technique of long tone contrast to show the snow scene on the cliff incisively and vividly. The long lines of calligraphy are intertwined with Jiao Mo's brush strokes, as if snowflakes are falling on the cliff, giving people a cold and fresh feeling. Landscape of Jiao Mo is a paper ink painting created by Pan Tianshou on 196 1, which is now in China Art Museum.
