What it is

A network of stations a day's ride apart, with relay mounts and provisions, available to bearers of the safe-conduct tablet (paiza). It came to link Beijing with the Volga and Persia, carrying messages more than 300 km a day.

Heir to the Chinese (yi) and Persian relay systems; the Secret History of the Mongols attributes its organisation to Ögedei.
