The Shanghai School (海上画派 Haishang Huapai or 海派 Haipai) is a very important Chinese school of traditional arts during the Qing Dynasty and the whole of the 20th century. Under efforts of masters from this school, traditional Chinese art reached another climax and continued to the present in forms of "Chinese painting" (中国画), or guohua (国画) for short. The Shanghai School challenged and broke the literati tradition of Chinese art, while also paying technical homage to the ancient masters and improving on existing traditional techniques. Members of this school were themselves educated literati who had come to question their very status and the purpose of art, and had anticipated the impending modernization of Chinese society. In an era of rapid social change, works from the Shanghai School were widely innovative and diverse, and often contained thoughtful yet subtle social commentary. The most well-known figures from this school are Ren Xiong (任熊), Ren Yi (任伯年, also known as Ren Bonian), Zhao Zhiqian (赵之谦), Wu Changshuo (吴昌硕), Sha Menghai (沙孟海, calligraphist), Pan Tianshou (潘天寿), Fu Baoshi (傅抱石). Other well-known painters are: Wang Zhen, XuGu, Zhang Xiong, Hu Yuan, and Yang Borun.
