High Quality Content by WIKIPEDIA articles! Xia Gui (Chinese: 夏圭 or 夏珪; Wade-Giles: Hsia Kuei, style name Yüyü) (fl. 1195-1224) was a Chinese landscape painter of the Song Dynasty. Very little is known about his life, and only a few of his works survive, but he is generally considered one of China's greatest artists. He continued the tradition of Li Tang, further simplifying the earlier Song style to achieve a more immediate, striking effect. Together with Ma Yuan, he founded the so-called Ma-Xia (夏馬) school, one of the most important of the period.
