敦煌、吐鲁番文书中与粟特人关系密切的翟氏一直受到学界的关注,但通常都仅是推测他们来自粟特地区或应为粟特人。本文通过分析发现,这些翟氏人物的名字基本已粟特化,他们通晓粟特语,与粟特人一起从事商贩交易,并广泛与粟特人通婚,甚至信奉祆教。因此,本文认为这些与粟特人关系密切的翟氏就是粟特人,源于康居。 Zhai, who is closely related to the Sogdians in Dunhuang and Turpan, has always been the subject of academic attention, but usually only speculates that they are from the Sogdian region or should be Sogdians. The analysis of this article found that the names of these Zhai people have basically been Sogdianized. They know the Sogdian language, trade with the Sogdian traders, and they marry widely with the Sogdian people. They even believe in religion. Therefore, this paper argues that Zhai, who is closely related to Sogdian, is a Sogdian, born of Kangju.
