Čïn bitig in Uighur Script is Qin-Qs in Han Chinese
(53rd Annual Meeting of the PIAC, St. Petersburg 2010)
It is a common view by a lot of researchers,including those from the Chinese and other countries, that the word čïn of ancient Uighur language came from the Han word 真 (genuine or true) and the term čïn bitig equals the Han word Zhen-Qi (literally, true contract) . The paper argues that the best translation of the term čïn bitig is Qin-Qi.The phenomenon that some contracts in different language shared common characteristics reflects a close economical and cultural link between the inner land and frontier areas.
