okay this is cool. Mandarin is kinda logical, so people from Deguo speak dewen, people from Faguo speak fawen,etc. Naturally I want to say which languages I *can* sorta understand so... people for Russia, EYUOSI, speak EYU. And similarly everyone in immediate contact with China (riben, hanguo, yuenan) has older forms. Equivalent to how the Russian for China and Chinese -kitai/kitaiskii - reflects an empire which hasn't existed for over a thousand years.
