In 1271, the Mongol Empire established an extensive postal system known as the Yam, which allowed for rapid communication across vast territories. This system utilized relay stations and mounted couriers, facilitating trade and governance from Mongolia to China. The efficiency of the Yam played a crucial role in the administration of the empire and helped to connect diverse cultures and ideas.

The Mongol postal system significantly influenced the spread of literature and ideas across Asia. It allowed poets and scholars to exchange works and thoughts more freely, contributing to the cross-pollination of literary traditions. The ease of communication fostered by the Yam likely inspired poets like Jami and Rumi, who were influenced by the cultural exchanges facilitated by the Mongol Empire.
