"The (Kök) Türük (突厥) are a separate branch of the Xuŋa (匈奴) with the clan name of Aşın (阿史那). At one point, their clan was nearly destroyed by neighboring states. The only survivor was a boy of ten. The soldiers, seeing that he was young, were reluctant to kill him. So, they cut off his feet and left him in the middle of a marsh. He was found by a she-wolf who nursed him back to health with meat. In time, the boy grew and mated with the she-wolf, leaving her pregnant. The king heard of this and dispatched troops to kill them. His envoy found the wolf laying on her side and desired to kill her. The wolf (noticed and) immediately escaped the envoy, fleeing to the northern mountains of Qoço (高昌). In the mountains, there was a cavern of flat land and lush vegetation. It had a circumference of several hundred li (里) and was surrounded on all four sides by mountains. The wolf hid here and gave birth to ten sons. Here, the ten sons grew strong. They brought back women from the outside, who soon became pregnant. Thereafter, each son had their own surname. One of these was Aşın. Each generation raised another, increasing their numbers until they numbered 100 households. After many generations, they (eventually) decided to leave the cave, (thereupon) becoming vassals of the Naıran. They made their home on the southern side of the Altay mountains, where they became blacksmiths for the Naıran. Since the Altay mountains are said to resemble a cauldron, and because it was their custom to call a cauldron Türük, they called themselves Türük."

"It is said that the "High Carts" (高車) are the remnants of the ancient Red *Täg(äräk) (赤狄). In former times, they were known as the *Tägäräk (狄歷). In the North they are known as the *Çägäräk (勑勒). The Chinese know them as the "High Carts" (高車) or *Tägäräk (丁零). Their language is similar to that of the Xuŋa (匈奴) but with the occasional minor differences, (thus) they may have been kin to the ancient Xuŋa. Their tribes are the *Täg(äräk) (狄), the Uyǧur (袁紇), the Hu-lu (斛律), the Qi-bi (解批), the Qırǧız (護骨), and the Yi-qi-jin (異奇斤).

It is said that the Darğa (單于) of the Xuŋa had two daughters that were so beautiful that the people wondered if they were goddesses. And so the Darğa said, "How will I find worthy matches for my daughters now! I must offer them to Heaven!" Thus, an uninhabited land was chosen for the construction of a high platform upon which he placed his two daughters. Afterwards, he said "I request that Heaven welcome them!" After three years had passed, their mother wished to greet them home, but the Darğa said, "You cannot, it is not yet their time." Thereupon, an ancient wolf appeared the following year, howling and guarding the platform day and night. It dug for itself a cavern under the platform, which it would not leave. The younger daughter proclaimed, "Our father placed us here, hoping that Heaven would take us. This wolf that has appeared here must be from Heaven!" The elder sister was mortified, and as the younger sister made her way towards the wolf, the elder sister proclaimed that "the wolf is but a wild animal. Do not bring shame to mother and father!" The younger sister did not listen to the words. She approached the wolf beneath and mated with it, giving birth to a child, whose descendants formed prosperous nations. Hence, her descendants still sing long songs in imitation of the wolf's howling."
