The different editions of this work , related documents , the intention of the author , his theories of poetics and its influence on later writers are all analyzed . This article is divided into the following six sections: 1. Preface : The aim and the outline of this study , 2. The intention of the author of the T'an lung lu : Based on Chao's own preface to the work , the author discusses its literary background . Chao's theories as distinct from those of Wang Shih-chen 王士禎(1634-1711) might have been influenced by his association with the literary circle in the South , which included writers like Yen Juo-ch'u 閻若璩 and Ku I-an 顧以安 . 3. The first argument : In this section Chao's criticism of Wang's poetry , poetics , and personality is discussed together with the reasons for Chao's relentless criticism . 4. The second argument : Chao's own poetics is discussed . The author discovers that as much influenced as Chao was by people like Feng Pan 馮班 and Wu Ch'iao 吳喬 , his poetics were mainly composed as a criticism of Wang Shih-chen . 5. The influence of the T'an lung lu : How later generations have thought about the work is discussed in this section . 6. Conclusion : Six conclusions are drawn here.
