He appointed his brother Kul Tigin to be Left Wise Prince, which made second most powerful person in realm.

Tang chancellor Wang Jun, believing that the Göktürks who surrendered would try to flee back to the Göktürk state, suggested that they be forcibly moved into the heart of the empire to prevent them from doing so.

Before Wang's suggestion could be acted upon, however, there was an uprising by the Göktürks who surrendered, under the leadership of Xiedie Sitai (𨁂跌思泰) and Axilan (阿悉爛).

Xue and Wang tried to intercept them and dealt them defeats, but they were able to flee back to the Göktürk state anyway.

While the Turks' power rested on their mobility, conversion to Buddhism would bring pacifism among the population.

[3] Emperor Xuanzong also recruited Qapaghan Khagan's sons Bilgä Tigin and Mo Tigin, Yenisei Kyrgyz Qaghan Kutluk Bilgä Qaghan and Huoba Guiren to fight against Tujue.

In 727, he sent Buyruk Chor (Chinese: 梅錄啜/梅录啜; pinyin: Méilù Chuò) as an emissary to Xuanzong with 30 horses as a gift.

On 27 February 731, Kul Tigin died, for which Qaghan mourned and ordered a great funeral ceremony.
