On Yuan Chwang's Travels in India, 629–645 A.D. v2.c21.s4.2

v2.c21.s4.2

To the east of Kāmarūpa, the description continues, the country was a series of hills and hillocks without any principal city, and it reached to the south-west barbarians [of China], hence the inhabitants were akin to the Man and the Lao. The pilgrim learned from the people [of Kāmarūpa] that the south-west borders of Szüchuan were distant about two months' journey, but the mountains and rivers were hard to pass, there were pestilential vapours and poisonous snakes and herbs. In the south-east of the country were wild elephants which ravaged in herds, and so there was a good supply of elephants for war purposes.
