Marco Polo's journey continues through the vast interior of Cathay, capturing the administrative and geographic layout of thirteenth-century Asia under Kúblái Khan's dominion. The narrative details the passage through populous northern cities, the great stone bridges across major rivers, and the transition into mountainous frontier regions.
The traveller records the distinctive domestic and social customs encountered along the route, from the peculiar marriage traditions of remote hill tribes to the widespread reliance on salt cakes and porcelain shells as currency. Particular attention is given to the natural products of each territory, including abundant silk production, musk, gold-dust, and local spices.
Moving southward into the immense province of Karajang, the account describes the capital city of Yachi and the ancient seat of Tali-fu, reflecting the administrative divisions established by the Mongol rulers. The narrative outlines the ethnological variety of the region, noting the presence of Mahomedans, Nestorian Christians, and various indigenous groups alongside Chinese settlers.
A significant episode recounts the military conflict in the borderlands of Vochan, where a small force of Mongol cavalry under Násruddin successfully repelled an invading Burmese army equipped with war-elephants. The tactical retreat into the forest and the rout of the enemy beasts are detailed as decisive factors in securing the Khan's authority.
The journey ultimately extends through the southern provinces towards the borders of India, recording navigational methods on great rivers, exotic fauna such as crocodiles and wild oxen, and the diverse religious practices and superstitions of the native populations.
