Tannu Uriankhai
The Tannu Uriankhai were reorganized into an administrative system similar to that of Mongolia, with five khoshuns ("banner") and 46 or 47 sumuns ("arrow") (Chinese and Russian sources differ on the number of khoshuns and sumuns). Each khoshun was governed by an hereditary prince nominally appointed by the Qing military governor at Uliastai. In the latter half of the 18th century, one of the khoshun princes was placed in charge of the others as governor ("amban-noyon") in recognition of his military service to the dynasty.
