The Great Chinese Art Revolution

Following the Cultural Revolution, art schools and professional organizations were reinstated. Exchanges were set up with groups of foreign artists, and Chinese artists began to experiment with new subjects and techniques. One particular case of freehand style (xieyi hua) may be noted in the work of the child prodigy Wang Yani -born 1975- who started painting at age 3 and has since considerably contributed to the exercise of the style in contemporary artwork.
