According to the inscription on this work by the Yüan dynasty connoisseur K'o Chiu-ssu (1290-1343), this is a painting of Mount Lu (in southern Chiu-chiang County, Kiangsi). Lofty mountains rise vertically layer-upon-layer, forming vast ravines with a vase sense of space from one peak to another. Modeled in short, rounded texture strokes, the artist has conveyed the rugged antiquity of the mountains.This work is traditionally attributed to Ching Hao, a native of Honan who lived in seclusion in the Hung Valley located in the T'ai-hang mountains, after which he took the sobriquet "Man of Hung Valley." He excelled at landscape painting, paying special attention to the use of the brush and variations in ink.
