Abstract: As a master of NeoConfucianism in the Song Dynasty, Zhu Xi wrote many ancientstyle essays which were related to his studies on Confucian classics .The relationship between his studies on classics and essays deserves attention. Zhu often quoted from the Book of History in creating his memorials to the emperor in order to give some advice to him and lead him to accept the system of his own NeoConfucianism. He paid more attention to his feelings, experiences and interests in reading Confucian classics than those Confucians in the Northern Song, and expressed his tastes in his writing ancientstyle essays. In his writing styles of “record” and “preface”, he deepened these essays’ theses by his interpretations or reflections of classics. His essays are therefore rich in their implications.
