That's interesting....I think this factoid reiterates the close connections between the Mongols and the Huns. When Genghiz Khan died, the Mongols had to transport his body from present-day Tibet (then called Si-Sa). To keep the death and the preparations a secret, they killed EVERY human and animal on the long journey home to Mongolia.
After that, they buried Genghiz Khan in the Burkan Kaldun mountain range, reshaped the mountain he was buried in, and ensured that no non-Mongol could ever reach the mountains in the next few hundred years (so that the place would be forgotten to history and wild forest growth).
Even today, modern Mongols continue to make fools of the considerale number of Japanese researchers who have been trying to find Genghiz Khan's tomb.
yup...
