History is recorded on paper, not on blogs so you’re not going to find it on internet or Wikipedia but yes if you visit Library Archives, they might just have a copy of writings that Genghis’s wife dictated. They are in Chinese Clerkly Script so you might have to get an English translation. Oh and it’s an accepted fact among historians that Genghis’s history was written by his rivals. Hence his character, which inspired a nation to rise above the divisions of the past, gets lost. 
You’re too kind.
