“不兰奚赤”来源于蒙古草原上管理遗失物的制度,阑遗监的设立是这一草原职役官署化的表现。“不兰奚赤”借着拘收“不兰奚”人畜的名号给元代社会带来严重骚扰,元廷屡降诏旨禁止不兰奚赤,后期采取了蒙汉南北分治的政策,反映了朝廷与投下诸王贵戚之间争夺劳动力的斗争。阑遗监的设立并未触及蒙元王朝的驱奴领主私属制,这是“不兰奚赤”屡禁不止的根本原因。 “Not Lan Xi red ” comes from the management of the lost grassland in Mongolia grassland system, the establishment of a lantern supervision is the performance of the office of the grass-roots official servant. “No Lanxi red ” By arrest “not Lan Xi ” the name of people and animals to bring serious harassment to the society of Yuan Dynasty, the imperial edict repeatedly banned not Lan Xi red, later adopted the Mongolian Han north The policy of dividing the country and the government reflects the struggle between the court and the sacrifice of the labor force by throwing the knights in charge. The establishment of the imprisonment did not touch on the private ownership of the slave-slave lords in the Mongolian dynasty. This is the root cause of repeated imprisonment.
