Abstract: Listed among the Top Four of the Yuan Dynasty (1279-1368), Ni Zan attained equally outstanding achievement as a calligrapher of the hermitage school as an artist. Natural, not luxurious and somewhat far from the madding crowd, the style of his calligraphy promoted the poem-calligraphy-painting trinity to a new height. Departing from the prefaces and postscripts of Ni Zan's calligraphy works, the paper focuses on analysis of the unique quality of his fine-size works, the affinity between the style of calligraphy and the artistic attainment of painting, and the seals attached to his calligraphy works, so as to explore an unbeaten track in the study of Ni Zan and his calligraphy.

Key words: Ni Zan, preface, postscript, calligraphy, seal
