While "Cambaluc" was known to European geographers, its exact location – or its identity with Beijing – was not quite clear. This map from 1610 repeats a fairly common pattern for the period: it shows two Khanbaliqs ("Combalich" in the land of "Kitaisk" on the Ob River and "Cambalu" in "Cataia" north of the Great Wall) and one Beijing ("Paquin", at its correct location in "Xuntien" prefecture).
Khanbaliq is the direct predecessor to modern Beijing. Several stations of Line 10 and Line 13 are named after the gates of Dadu.
