Reign
In 618 or 625 Tong Yabgu invaded Tokharistan and forced Hephthalite principalities to submit. According to Cefu Yuangui, these principalities were Zabulistan, Kapisa-Gandhara, Khuttal, Chaghaniyan, Shignan, Shuman, Badhgis, Wakhan, Guzgan, Bamiyan, Kobadiyan and Badakhshan, when Pantu Nili – a later yabgu of Tokharistan submitted to Tang. He installed his son Tardu in Kunduz to rule over with title of Tokharistan Yabgu.
He was married two times, both times to a daughter of Qu Boya ruler of Gaochang. When Xuanzang visited Kunduz, he also brought a letter from his brother-in-law and ruler of Gaochang Qu Wentai to Tardu. Yabgu received him despite being ill. Tardu advised him to make a trip westward to Balkh, to see Buddhist sites and relics. Xuanzang also witnessed a palace scandal when Tardu's firstborn son Ishbara Tegin fell in love with his new step-mother and poisoned Tardu in 630.
