The Tibetan Empire reached its greatest extent under his rule, and included parts of China, India, Nepal, the Kingdom of Khotan, Balti, Bruzha (Gilgit and Hunza), Zhangzhung, Hor-yul, Sog-yul, Yugur, and Kamilog (roughly equivalent to present-day Sichuan), as well as almost all of modern Xinjiang and Gansu.
