越南漢文燕行文獻的新發現：西山朝佚名《使程詩集》作者考辨

A New Discovery of Vietnam Chinese Yanxing Literature: An Analysis of the Author of Shi Cheng Shi Ji by Tay Son Dynasty

《越南漢文燕行文獻集成（越南所藏編）》第8冊，已將越南漢喃研究院所藏編號A.1123的《使程詩集》複印公開，並且認定該書作者絕非書上所署的潘清簡（1796-1867），而是西山朝某位佚名赴華使節，至於是誰則無從知曉。學界探討該部漢詩集的作者問題，或以為係與西山朝使臣阮偍（1761-1805）同行者，或主張非一人一時之作。本文作者透過文獻爬梳與田野考察，取得了最新的研究發現，確定它是一位西山朝使節的漢文詩作，而且姓名俱在。這位西山朝使節正是阮世直，又名阮曰直（1745-1807），景盛元年（1793）他與正使吳時任（1746-1803）、乙副使阮文寀同行北使告哀求封，吳時任撰有《皇華圖譜》，阮世直也寫下《使程詩集》，為越南與中國的外交與文學交流留下珍貴的記錄。西山朝佚名《使程詩集》的作者考辨，既確定了該部詩集作者的真實身分，增強文獻可信度，同時也為越南廣平麗水阮世家族找到了二百多年前第八代祖先阮世直的遺作，可視為廣平省歷史名人與文化資產的重要新發現。

The 8^(th) volume of the Collection of Vietnamese Chinese Yanxing Literature (Collected by Vietnam) has been copied and published by the Institute of Han-Nom Studies, with the No. A.1123 of Shi Cheng Shi Ji, and it is determined that Phan Thanh Gian (1796-1867) is not the author, but it was an anonymous envoy (who is unknown) to China in Tay Son Dynasty. The scholar has discussed about the authors of the poetry, by thinking that he was the envoy who accompany with Nguyen De (1761-1805) or the poetry was not created by one person. This paper has obtained the latest research findings through literature reviews and field investigation, and it is confirmed that is a Chinese poem written by an envoy of Tay Son Dynasty, and his name can be checked and verified. This envoy was Nguyen Thi Truc, also known as Nguyen Viet Truc (1745-1807). In the first year of Jing Sheng (1793), he accompanied with the ambassador Ngo Thoi Nhiem (1746-1803) and deputy ambassador, Nguyen Van Chay, to beg for a bestowed by the emperor of Qing. Ngo Thoi Nhiem had written a book called Huang Hua Tu Pu, and Nguyen Thi Truc also wrote a poetry called Shi Cheng Shi Ji, which left precious records for diplomatic and literary exchanges between Vietnam and China. The identification of the author not only confirms the identity of the author of the poetry, it enhances the credibility of the literature, but also finds out the legacy of the 8^(th) generation ancestor's Nguyen Thi Truc more than 200 years ago for the Nguyen's family of LệThủy district, Quang Binh Province in the North Central Coast of Vietnam, which can be regarded as an new discovery of historical personalities and cultural assets in Quang Binh Province.
