敦煌文献
The variety of languages and scripts found among the Dunhuang manuscripts is a result of the multicultural nature of the region in the first millennium AD. The largest proportion of the manuscripts are written in Chinese, both Classical and, to a lesser extent, vernacular Chinese. Most manuscripts, including Buddhist texts, are written in Kaishu or 'regular script', while others are written in the cursive Xingshu or 'running script'. An unusual feature of the Dunhuang manuscripts dating from the 9th and 10th centuries is that some appear to have been written with a hard stylus rather than with a brush. According to Akira Fujieda this was due to the lack of materials for constructing brushes in Dunhuang after the Tibetan occupation in the late 8th century.
