Jurchen script
Due to the scarcity of the surviving samples of Jurchen writing, it was often difficult to determine for the 19th-century (or sometimes even 20th-century) scholars, whether a given inscription was in the "large" or "small" Jurchen script, or whether it was in Jurchen script at all. Thus, it was commonly thought in the 19th century by the Chinese and Western researchers that the "Da Jin huang di doutong jinglüe langjun xingji" () inscription represented the Jurchen large script until, in 1922, the Belgian missionary L. Ker discovered the Liao Imperial Tombs in Qingling, where this very script was used, in parallel with Chinese text, for the epitaph of Emperor Xingzong of Liao and Empress Renyi. Thus the Khitan script was discovered, and the Jin dynasty's "Da Jin huangdi dotong jinglüe langjun xingji" inscription, long thought to be written in Jurchen script, turned out to be written in the (still undeciphered) Khitan script and, most likely, Khitan language, after all.
