According to Old Tibetan Annals, in 690, Tsenba corrected taxes in g.yo ru (a place in modern Nêdong District, Shannan, Tibet) together with ba tsab rgyal tsan thong bo.
The Chinese troops led by Wang Xiaojie and Lou Shide invaded Tibet in 696, but was utterly beaten by Tsenba and his brother Gar Trinring.
In 699, the king pretended to organise a great hunt and then had his men turn on members of the Gar and their supporters.
After hearing about this, Tsenba surrendered to China together with his nephew Mangpoje (known as Lun Gongren (論弓仁) by Chinese).
The Chinese empress Wu Zetian was very happy, met him personally and titled him Tejin (特進), Right Guard Senior General (右衛大將軍) and Prince of Guide Commandery (歸德郡王).
