[The Dunhuang Fragment ДX17453 of the <i>Su Wen</i>].

The Dunhuang fragment ДX17453 in <i>Dun Huang Literature in Russia (E Cang Dun Huang Wen Xian)</i>, was believed to be a related version of <i>Su Wen</i>. It was previously taken as a version based on the <i>Su Wen</i> annotated by Wang Bing. However, the content of ДX17453 differs from the annotated edition by Wang Bing in terms of format and content. It was found that the ДX17453 should be the original version before the annotated edition by Wang Bing, sharing the same original manuscript with the annotated edition by Wang Bing. The format of the fragment ДX17453 took a Tibetan style, which might mean it was produced in the period of the Tibetan regime (786-848). These findings provide references for investigating the popularity of <i>Su Wen</i> before the Song Dynasty.
