Chinese sources indicate that the Xiongnu did not have an ideographic form of writing like Chinese, but in the 2nd century BC, a renegade Chinese dignitary Yue "taught the Shanyu to write official letters to the Chinese court on a wooden tablet 31 cm long, and to use a seal and large-sized folder." The same sources tell that when the Xiongnu noted down something or transmitted a message, they made cuts on a piece of wood ('ke-mu'), and they also mention a "Hu script" (vol. 110). At Noin-Ula and other Xiongnu burial sites in Mongolia and the region north of Lake Baikal, among the objects discovered during excavations conducted between 1924 and 1925 were over 20 carved characters. Most of these characters are either identical or very similar to letters of the Old Turkic alphabet of the Early Middle Ages found on the Eurasian steppes. From this, some specialists conclude that the Xiongnu used a script similar to the ancient Eurasian runiform, and that this alphabet was a basis for later Turkic writing.
