, at the time when the Yenisei Kyrgyz were taking over the region. 5th-6th century CE. The
Tang Huiyao (961 CE), citing the
Protector General of Anxi Ge Jiayun, states that the Kyrgyz, known to the Chinese as the Jiankun, all had red hair and green eyes. The ones with dark eyes and black hair were believed to be descended from
Li Ling, a
Han dynasty general whom the Kyrgyz claimed to have married a Kyrgyz woman and was sent to aid in their governance after he surrendered to the Xiongnu. The name Jiankun was later changed to
Xiajiasi; according to a translation clerk,
Xiajiasi meant "yellow head and red face" and this was what the Uyghurs called them; Pulleyblank (1990) proposes that "yellow head and red face" was a
folk etymology based on
Turkic qizqil ~
qïzïl "red". From
Xiajiasi 黠戛斯,
Soviet scientists constructed the new exonym
Khakass.
Edwin G. Pulleyblank surmises that "red face and yellow head" meaning was possibly a
folk etymology provided by an interpreter who explained the ethnonym based on
Turkic qïzïl ~
qizqil, meaning 'red'. The description of the Kyrgyz as "large, with red hair, white faces, and green or blue eyes" in Tang Chinese sources have tempted a number of researchers to assume that the Kyrgyz may have originally been non-Turkic or at least an ethnically mixed people. American Turkologist Michael Drompp notes that the connection between language and race is highly inconclusive and the physical appearance of the Kyrgyz is no more credible an indicator of non-Turkic origin than a few possibly non-Turkic words in their lexicon, whose presence can be explained through linguistic borrowing. Yenisei Kyrgyz inscriptions in the eighth century and later are written completely in the Turkic language and Tang Chinese sources clearly state that the Kyrgyz wrote and spoke a language identical to the Uyghurs. Drompp states that there is no reason to assume the Kyrgyz were non-Turkic in origin, although such a possibility cannot be discounted. According to Lee & Kuang, who cite Chinese historical descriptions as well as genetic data, the turcophone "Qirghiz" may have been of non-Turkic origin, and were later Turkified through inter-tribal marriage. The Kyrgyz were described in the
You yang za zu by Duan Chengshi in the 9th century AD as people with yellow hair, green eyes, and red beards. According to Duan, the Kyrgyz were not of wolf descent, unlike the Turks, and were born in a cave north of Quman Mountain as the offspring of a god and a cow. The
New Book of Tang (11th century) did not consider the Kyrgyz to be the same as the Tiele tribes but states that they had the same language and script as the Uyghurs. The
New Book states that the Kyrgyz were "all tall and big and have red hair, white faces, and green eyes." They looked similar to the neighboring "Boma tribe" (
Basmyl), who did not share the same language, implying that the Kyrgyz may have originally been a non-Turkic people. Lee & Kuang consider the Kyrgyz to have been physically distinct from the "Kök Türks" because no similar description of their appearance exists while
Ashina Simo's ancestry was called into question for his "Hu" Sogdian appearance.
Gardizi believed the red hair and white skin of the Kyrgyz was explained by mixing with the "Saqlabs" (Slavs) while the
New Book states that the Kyrgyz intermixed with the
Dingling. ==Lifestyle==
