Lin Xiyi was a Confucianist in the late Southern Song Dynasty whose teacher was Chen Zao, a very famous scholar in Ai Xuan School. Lin Xiyi in his book, "Oral Significance of Zhuangzi", employs an oral way to explain Zhuangzi's ideas. Besides interpreting Zhuangzi from the perspective of Buddhism and Confucianism, he also changes the traditional method of interpreting the meaning of "Zhuangzi", paying close attention to "Zhuangzi's" literary achievements. Therefore, Li Xiyi not only makes a great many contributions to interpret Zhuangzi, but also has significant effects on the later scholars who try interpreting Zhuangzi. This paper will focuses on Lin's method of "Citing Confucianism to interpret Zhuangzi" to show "Oral Significance of Zhuangzi's" contribution in interpreting Zhuangzi; all of the arguments will be in four aspects. In Lin's opinion, through the extreme accounts of Zhuangzi, it is after all not contradictory with what Confucianists say. Therefore, Lin Xiyi cites the conceptions of Confucianism to combine "Zhuangzi". Because of the defense by Lin, "Oral Significance of Zhuangzi" becomes distinctively Confucianized. Moreover, Lin offers another of way of reading "Zhuangzi" which promotes the Confucianist's development in the Song Dynasty.
