 However, there is no one in the Liu family whose name sounds like "Kama Tarkhan".If Kama Tarkhan was of this same group, then he would have been related to Kidara of the Ki clan (of Yuezhi ethnicity), who led a Bactrian portion of Chionites to overthrow the Kushans in India.In this case he might have been the Chionite king Grumbat mentioned by Ammianus Marcellinus and included in the Kidara dynastic list of the Chionite Ki clan.
