Within the history of Chinese literature, Fan Chengda 范成大 (1126-1193) is one of the four great poets of the Southern Song dynasty; furthermore, his Wujun zhi 吳郡志, which was completed during the later period of his life, is also an important work for studies on local histories. This article concerns a seldom discussed question within related scholarship: what is the relation between poetry and writing local history? In other words, as Fan Chengda authored Wujun zhi, how did he arrange poems to formulate landscapes and convey the feeling of local history? This article is comprised of two main parts: (1) it illustrates the kind of innovative methods and new changes that Wujun zhi utilized to arrange poetry; (2) using descriptions of "landscapes" and "local objects of Wujun" as examples, this article elucidates that Fan Chengda employed four ways of arranging poems to write local history: choosing, exclusion, sequencing, and adjusting the focus of narrative. Therefore, the so-called of poems into local histories was not merely the listing of poetry in local history, but also demonstrates Fan Chengda deeply understood the meaning of the poems and the aspects of writing local history. In short, through its remarkable use of poetry, Wujun zhi shows a clearer and more vivid picture of local history, which has never been seen before.
