Others think it is a person or tribe's name. For example the Chinese name Kesa for "Khazars" may be one of the tribal names of the Uyğur Toquz Oğuz (of the Gokturks), namely the "Gésà". But others say Kesa was not a tribal name but the name of the chief of the 思结 "Sijie" tribe of the Toquz Oğuz. Also in Middle Chinese the name "Khazars" always comes before the word "Tūjué" ("Tūjué Kěsà bù": 突厥可薩部; "Tūjué Hésà": 突厥曷薩).
