Wu Guanzhong(吳冠中 1919-) is one of the persons who groped for the way of new Chinese modern painting with the mixing of East-West painting in Chinese modern painting circles. In addition, Wu Guanzhong is a ringleader who returned to Chinese ink(水墨)to be Chinese traditional material while trying making oil painting into Chinese painting after studying in France like Sue bai hong(徐悲鴻) and Lin peng mian(林風眠) who converted to Chinese painting while drawing oil painting after studying in France. That Wu Guanzhong is noticed in Chinese modern painting circles is that he achieved new abstract landscape of Chinese style with his own abstract method about the landscape to be the tradition subject of Chinese painting. Landscape of Wu Guanzhong aroused wide interest in Europe as well as Chinese modern painting circles. The reason is because he created the landscape of new style which is comprehensible in all the painting circles of the East and the West with Western modeling form to be abstraction, while sticking to landscape to be the traditional subject of China. Efforts that Chinese modern painting circles tried to create the Chinese painting of new period by borrowing Western modeling method has been treid by Lin peng mian(1990-1991) who was a teacher of Wu, Guanzhong. Walking of Wu Guanzhong is not irrelevant to the influence of Lin peng mian. But, it is different that the landscape of Lim peng mian investigated landscape form with whole mass sense to be surface, whereas the lanscape of Wu Guanzhong has interest about more linear spirit. Traditional painting of China came to realize reform since it recognized the existence of Western painting flowed in Chinese modern painting circles. After this, there was dispute between traditional school and reform school in Chinese modern painting circles, and all the two groups moved the recognition to have to draw new drawing to be suitable for period. But, about the newness, traditional school tried to change by finding from old thing, and reform school tried to create newness by grafting science and color of Western painting to Chinese painting. As for reform school, Sue bai hong(1895-1953) who insisted on the improvement movement of Chinese painting and Lin peng mian who insisted on East-West fine art harmony may be representatives. Lin peng mian educated the reform of Chinese painting with new catchpraise to be East-West fine art harmony, when he was as a principal of Seoho National Art Institute. Wu Guanzhong met Lin peng mian as a student of this school and came to walk as a reform school after that. In this study, Wu Guanzhong did new formal experiment by paling the issue of contents that Chinese traditional painting aimed at in secondary order while creating new drawing style with East-West fine art harmony and insisting that form decides contents. But, this researcher tried to search for the traditional issue of Chinese painting to be involved in modern landscape of Wu Guanzhong under the recognition that the landscape of Wu Guanzhong could not get out of the vein of eternal tradition of Chinese painting. That abstract landscape of Wu Guanzhong is extracting plastic beauty from nature(landscape) has character to be different from Western abstract painting of Mondrian kind which didn’t have relation with natural material. Then, drawing which was the basic starting point of Chinese painting from this abstract idea is same as the speculation to be the world of pictorial penetration for the image of nature and all things. In addition, most methods of picture composition of abstract landscape of Wu Guanzhong centering around form that he stood as newness are adopting the style of great masters of Chinese traditional landscape. And, he emphasized that brush and Chinese ink is not what must be learned but the expression technique of brush and Chinese ink must be learned, but it can be said that animation nature that he thought importantly in drawing is that cell division is made from atmosphere animation of traditional painting. However, that landscape of Wu Guanzhong is significant is that he drew the landscape in life. It is that he drew the modern landscape of new sight nature with the abstract method which doesn’t describe visible landscape in life concretely about traditional landscape which tried to reveal the invisible image of nature with concrete form. But, it will be fair to regard the abstract landscape of Wu Guanzhong as reinterpretation of tradition in that this conception was possible as there was entity to be traditional landscape.
