The Buddhist doctrinal texts from Dunhuang provide a genuine record of the debates among Buddhists in the Dunhuang region during the late Tang, Five Dynasties, and early Song periods. These texts document how Buddhists in Dunhuang engaged in debates using the question-and-answer format to explain concepts related to Buddhist numerical symbolism. There are 102 extant Buddhist doctrinal texts from Dunhuang, of which the academic community has fully or partially edited and collated 35 scrolls. However, due to the complexity of their content, the use of many variant characters, and common issues such as missing text and blurred writing, there are still some aspects deserving of discussion in the previous schola rs’ revisions. This article attempts to supplement the work of previous sages from the following aspects: 1. Corrections of unclear familiar characters; 2. Corrections of unclear ambiguous terminology; 3. Corrections of undefined borrowed characters; 4. Corrections of unclear allusions; 5. Corrections of dim literary writing styles; and 6. Corrections of blurred original scrolls.
