Jing Hao (Wade–Giles:Ching Hao, also known as Hongguzi) (c. 855-915) was a Chinese landscape painter and theorist of the Five Dynasties and Ten Kingdoms period in Northern China. As an artist, he is often cited along with his pupil, Guan Tong, as one of the most critical figures in the development of the style of monumental landscape painting which appeared near the end of the Five Dynasties period. Later this style would come to be known as the Northern Landscape style; it strongly influenced the tradition of Northern Song painters. As a theorist, he is the person most responsible for codifying the theories underlying the work of later painters, and his treatises on painting and aesthetics continued to serve as textbooks for Northern Song artists more than a century after his death.
