Wu Weishan is a unique figure in        Chinese art circle. His unrestrained personality is highlighted in his unconventional paintings. His brushwork is vigorous and forceful, and the lines are dazzling and mythical. By means of lines Wu can convey contours, light, surface, volume, solidity and rhythm.
    Wu is fond of painting trees, rocks, flowers and birds. In particular, he is interested in living creatures in the real life. In his artistic exploration, he tries to present varied aspects of life and express his understanding to the vitality of nature.
    His work “Echo in the Valley” is a good example. On the painting is a pine tree, a rock hidden in the grass and a bird resting on the rock. Viewers can see from the space between the tree and the rock that the bird is standing on the cliff. Its body leans forward and makes a good contrast against the twisting branches of the pine. It seems the bird is aroused by the sound of wind echoing in the valley. The artist creates an illusion of the sough of the wind without actually painting a stroke of it. Wu gives more thought and attention to the composition than to the objects depicted. He does not care if the image is accurate or what kind of bird he is painting. He is more concerned about the spirit and feelings he tries to convey in the painting.
    Chinese literati painting is much less concerned with technical showiness. Brushstrokes are seen as expressions of the spirit more than skill in realistic depiction.
