This paper takes Xiang-Yang's Taiwanese poetry published in periodicals and anthologies from 1976 to 2002 as range of study. There is two main observations: 1) A longitudinal observation on ”continuity”: This so-called continuity is the consistency of character using in one's different time and his different anthologies. Through the longitudinal research, we could unfold completely the various changes of character using in Xiang-Yang's Taiwanese poems each period. 2) A cross-sectional observation on ”the uniformity of character using”: Through the crosssectional exploration, we could realize whether he does use the fixed Chinese character to express identical word in each anthology. In this study I compared Xiang-Yang's Taiwanese poetry with the other Taiwanese poets, additionally I concluded the Xiang-Yang's inertia in character using, to find the changes from the early period to the later period.
