History of Liao
Khitan names are the personal names of the Khitan people which ruled the Liao Dynasty (907–1125) in ancient China and Kara-Khitan Khanate (1124–1218) in Central Asia. A nomadic Mongolic people, the Khitans have been extinct, making research on their cultures difficult. Currently the Khitan language has largely not been deciphered, and the presence of 2 different writing systems - the Khitan large script and the Khitan small script, make research more difficult. The problem is compounded by the fact that most of the Liao history were recorded in written Chinese such as "History of Liao", and transliteration into Chinese characters are not always standard even in modern days, much less in ancient days when the pronunciation is different as Chinese is logographic.
