An inscription on a stone stele was found near Nerchinsk in Siberia: "While Chinggis Khan was holding an assembly of Mongolian dignitaries, after his conquest of Sartaul (East Turkestan), Yesüngge (the son of Chinggis Khan's brother) shot a target at 335 alds (536 m)."
In the historical novel "Khökh Sudar" Injinashi, the Mongolian philosopher, historian and writer, imagines the competition amongst all Mongolian men in about 1194-1195: five archers each hit the target three times from a distance of 500 bows (1 bow = at least 1 metre).
