黎貴惇(1726-1784)是黎朝末年百科全書式的著名學者，著述豐富。本文所取材的《芸臺類語》與《見聞小錄》，從探討中國與越南文化交流的觀點而言，《芸臺類語》可見到中國人寫越南，而《見聞小錄》中可看見越南人談中國。黎貴惇的格物之學不止是博覽群書的興趣，更有經世致用的目的。他認為：事物隨著時空環境而產生沿革變異，然而變異正為了群體的相生相養、相規相保，也就是常道。他的格物方法是廣泛理解各種不同事物來體會其中的常道，而達到範圍曲成之妙。黎貴惇的思維是中國式的，但他從變異的重要性關注越南的風土人物，並強調越南青出於藍的實例。論文主體是抄錄二書裡中越交流的記述，並略作說明。分為四節：越南從遠古到獨立前後的歷史、中國官制的模仿、人員與技藝的交流、物產的交流。

Le Quy Don (1726-1784), the well known encyclopedic scholar of the late Le dynasty, left us tremendous literary works. This article introduces his descriptions and opinions of the cultural communication between China and Vietnam in his two books. In Yun-tai le-yu are found Chinese records of Vietnam people and things, and in the other book, Jian-wen xiao-lu, we see how Vietnam people thought about Chinese. With regards to Le Quy Don's Ge-wu learning, in addition to the interests of comprehensive learning, he aimed at practical administrations of world affairs. He believes that things changed with times and spaces. However, these changes must be utilized to bring benefits and give orders to the lives of people, which is the development of the constant way. The purpose of Ge-wu is to learn the constant way through investigation of different things, in order to helping people adapt themselves to changing situations. Although equipped with the Chinese way of thinking, he recognized the importance of changes and gave great concerns about Vietnam things, and illustrated examples of superior development of the latter. The main parts of the article are discussions of the citations and comments which Le Quy Don made from Chinese and Vietnamese sources. The discussions are divided into four sections, which are 1) Vietnamese history before and around independence, 2) imitations of Chinese political system, 3) interactions of people and crafts, and 4) communications of products.
