Once a bookseller threw in a free book for him, which turned out to be a copy of the Prajna Paramita Sutra printed in the sixth year of the Chih Cheng reign of the Yuan dynasty (1346). The book was printed using characters carved from patterns hand-done by the poet Su Tung-po, and the calligraphy and illustrations were both exceptionally beautiful.
一位書商隨手附贈給他的一本書，竟是元朝至正六年刻的《金剛經》，這本經書是以蘇東坡的手寫體刻的，圖文都非常精美。
