The Northern Wei started to arrange for Chinese elites to marry daughters of the Xianbei Tuoba royal family in the 480s. More than fifty percent of Tuoba Xianbei princesses of the Northern Wei were married to southern Chinese men from the imperial families and aristocrats from southern China of the Southern dynasties who defected and moved north to join the Northern Wei.
