Guan Liang was the first generation of oil painters in China. He went to Japan to study Western painting techniques in 1917 and was strongly influenced by the Japanese Fauvism of the Impressionists. He devoted his whole life in art creation after returning to China. He was famous for his reformed oil painting with a national tone, and vivid opera figures in Chinese Paintings. Guan Liang not only emphasized the learning of the tradition but also of the modern. His paintings are the reflection of cultural development in today's world as well as contemporaneity. "Under the Old wall" displays the artist's skillfully realistic style, reflecting the artist's claim to incorporate sentiment of Chinese arts into western arts.
