Geshu Han
It is not known when Geshu Han was born. His paternal ancestors were tribal chiefs of Western Turkic extraction, bearing the Nushibi Geshu surname and belonging to the Duolu Tuqishi tribe. His grandfather Geshu Ju () served as an officer in the Tang army, and his father Geshu Daoyuan () served as the deputy to the Protectorate General to Pacify the West, and thus lived in Anxi Circuit (安西, headquartered in modern Aksu Prefecture, Xinjiang). His mother was a Khotanese princess. Geshu Han's household was said to be rich, and he used the wealth to further what he saw were just causes, and he also drank heavily. When he was 39, his father died, and he spent three years in the Tang capital Chang'an. On one occasion, he was disrespected by the sheriff of Chang'an County, and he took this disrespect as a reason to serve in the military.
