There are many classic Chinese books on the events happened between China and Southeast Asian nations in ancient times. In due to the insufficient geographical knowledge in this region, so there are many unidentified nations and tribe n ames in classic books.

In this paper, I try to collect the sources on the relations between Song Dynasty and Southeast Asia by chronological method, and referring to different sources to note one historical event in order to show the historical mosaic.
