《六朝選詩定論》乃清初重要之評注本，單由視覺即可見吳的獨到見解。他對俯視仰觀之闡釋，展現單純物色句中人活動的身影，可見他對人主體性之重視；原詩已見俯仰字眼者，則以闡明背後深意為主。在「望」的闡發中，吳重視「即使不見目標物仍堅持遠望」之情，而在視覺流轉的闡述中強化情思。至於望與空間方位，則可見客觀距離中的主觀情思；眺望某空間所生之歷史懷想；對南北的闡發則可納入士人重視君臣家國的傳統。至於顧望與徘徊佇立的限定搭配，可見兩者連動的樣貌，吳對身體共振引發情思之關鍵性誠多所留意。光覺部分吳費心闡述虛幻難掌握之光影，並指出光影較其他實景更能塑造挑動情思之氛圍。誰之「見界」的分析，則提供讀者多元觀看詩歌的視角。吳視覺闡發乃尊經主張之具體實踐，能發人所未發，可見於詩評史上之價值。

Liuchao xuanshi dinglun have a lot of insightful poetry reviews in the early Qing dynasty. Wu Qi's special insight can be seen from his visual observations. From the explanation of looking up and down, Wu Qi demonstrated human activities in sentences of poems purely describing objects by means of vision, from which we see Wu's emphasis on the subjectivity of human beings. If the phrases of looking up and down explicitly appeared in poems, Wu focused on the explanation of insights behind poems. In the explanation of looking forward, Wu Qi emphasized on the emotion about ＂even poets cannot see the targets, they still insist on looking forward＂. It will strengthen poem emotions by Wu's expounding on flows of sights. As to ＂looking forward＂ and ＂space and locality＂, we can see subjective feelings in his explanation of objective distances. Besides, Wu showed historical thinking on the exploration of overlooking a certain space. His elucidation about north and south could bring in the tradition which scholars attach importance to monarch and emperor. When the view is limited with wandering and standing, we can see gearing between both things. Wu paid more attention on criticality body resonance triggering for emotions and thought. In the appearance of lighting, we discuss how Wu Qi carefully explained illusory and changeable light and shadows. He showed that light and shadows could more vividly create an atmosphere for arousing poem affection than other real objects did. Finally, the analysis of ＂Who observes the objects?＂ could provide readers different perspectives on reading poetry. Wu Qi's explanation of vision is a specific practice of his respecting classic proposition. His poetry reviews contain ideas that have not been explored before. The value of Wu's poetry reviews in history of poetry criticisms is therefore clear and explicit.
