唐史论丛

<正>引言2004年刊布的出土于陕西省西安市东郊的《赠尚衣奉御井公墓志文并序》，是日本人井真成的墓志。这方墓志引起了日本古代史学界的广泛关注，学者们讨论激烈，众说纷纭，最终得出井真成为留学生的结论^[1]。然而，将井真成视为无品级的留学生这一看法令人疑惑。无品级的留学生客死长安，却被授予从五品上的“赠尚衣奉御”，唐朝无缘无故地向一位白身留学生授予“赠尚衣奉御”的官职，这在唐代的制度下是不可能发生的。

The mainstream academic views on Jing Zhencheng's identity are represented by the “foreign student” and the “associate judge of the Japanese envoys to Tang China.”Based on Professor Han Sheng's “associate judge of the Japanese envoys to Tang China theory” and the “borrowing rank system” of the Japanese envoys to Tang China, this paper argues that Jing Zhencheng was one of the four clerks in the tenth mission of Japanese envoys to Tang China. Originally ranked as the seventh grade, upon arrival in Tang China, his rank was equivalent to the sixth grade according to the “borrowed rank system”, and was regarded by the Tang Dynasty as a third-class official on par with the judge of the Japanese envoys,enjoying privileges granted to foreign envoys by the Tang Dynasty. After his death, he was posthumously awarded the rank of Shangyi Fengyu(a court officer responsible for imperial attire), which was a higher grade than his previous rank. Meanwhile,this paper reconstructs Jing Zhencheng's posthumous appointment document and, by examining the appointment of foreign envoys in the Tang Dynasty, concludes that the “posthumous award of Shangyi Fengyu” to Jing Zhencheng was not an actual appointment but an honorary one.
