Born in Chinchou, Shandong, he graduated from the National Normal University art department, and initiated the Fifth Moon Group, arduously promoting the Taiwan modern art movement. When he was twenty-seven years old, he deeply felt the importance of national characteristics and cultural traditions, he was like a man on a mission, to find for twentieth century Chiniese drawing a new tradition to be spared no effort, and gave brush ink in traditional Chinese paintings a new definition, and promoted the theory of "texture with the brush". This kind of Chinese traditional painting doesn't need a pen to be painted, although receiving criticism at the time, at present, including mainland painters, critics as well as art historians, have all accepted this idea. Liu Kuo-sung also puts to this kind of theory the implemention with, in his individual practices, innovating with the color and ink techniques for more than 30 years, creating many kinds of different forms and individual styles.
