Because he was an extraordinarily talented person, Yuan was recommended to be the Dean of the Li-tse Academy. Later, because of his erudition, he was promoted to be a Provisioner of the Hanlin Academy and Concurrent Junior Compiler of the Historiography Institute. He was then appointed as an Auxiliary in the Academy of Scholarly Worthies and later transferred to the post of Expositor-in-Waiting. He was also enfeoffed as Duke of Ch'en-liu and given the posthumous title Wen-ch'ing. Calligraphy histories record that Yuan's style developed from the styles of the Chin (265-420) and T'ang (618-906) dynasties. The brush method used to execute this letter was swift and sharp, and the strength of the brush was heavy. Many of the perpendicular and downward strokes often slant to the lower right, and the characters seem to slant up to the right. The style of this work seems to demonstrate the influence of Su Shih (1036-1101)
