Shahai Buddhist Lantern

This book takes a look at the historical events of Zhang Yichao's recovery of the Hexi Corridor in the late Tang Dynasty. At this time, Tubo's national power was declining due to civil strife. Zhang Yichao led the people of all ethnic groups in Shazhou to launch an uprising, successfully expelled the Tibetan garrison and recovered Shazhou. Subsequently, using Shazhou as the base, they gradually recovered the eleven prefectures (eighteen divisions) of Hexi including Guazhou, Suzhou, and Ganzhou.
