Jami' al-tawarikh
Most of his life is described in "The Secret History of the Mongols" and "Jami' al-tawarikh". He was fifth son of his father. He was described as brave and courageous ruler. He pursued alliance with Keraits, namely Toghrul against Tatars and Jin Dynasty. He pillaged Tatars in retaliation of Ambaghai and his own brother, Ökin Barkak's kidnapping and execution, along with his nephews Qadaan Taishi and Yesugei. Despite the fact that the Mongols thirteen times clashed with the Tatar leaders Qoton Baraq and Jali Buqa, they did not manage to achieve a decisive advantage. He was ambushed after returning from his raid by Dörben tribe and was assumed dead by Yesugei and his kinsmen. He later died fighting the Tatars, who were aided by Jin Dynasty in 1161.
