Publications related to Jie-ju (truncated lines) grow continuously. With the creation and initiation made by poets, such as Tsu-huang Chuang and Shui-shun Hsiao, truncated lines have become a trend. The ways of composing truncated lines are different from that of typical modern poems, such as narrative structures-the internal and external structures. Besides, truncated lines show the challenges of "imagery." A good poem emphasizes on its narrative, sound effects, and imagery construction. It leads the target readers to understand the work through the writer's presentation. Thus, poetry writing tends to be concerned with the positive effect of the imagery and the proper control of metaphors; on the contrary, the control of imagery on the "truncated" "boundary" of Jie-ju or the imagery communication with the expected readers are important standards in the review of Jie-ju. Hence, this study will elaborate on the imagery construction and then the development or challenge of writing truncated lines, in order to enrich the truncated lines scholarship.
