Place names based on traditional Chinese knowledge and Islamic knowledge coexist separately. Their boundary line can be drawn from Besh Baliq to Delhi. Names based on Chinese geography were placed to the north and east of Besh Baliq even if they are actually located to the west. For example, the Talas River, a historic site for the Tang Dynasty, was placed to the northeast of Besh Baliq although its actual direction is northwest. Similarly, India and Tibet are based on traditional Chinese knowledge, mainly gained by Buddhist pilgrimage up to the Tang Dynasty. To the west of the "old" India, contemporary place names of India such as Delhi, Badaun and Duwayjir∼Duwayqir (Persianized form of Devagiri) are shown. This suggests that information was acquired via the Ilkhanate.
