Zhao Gong's 趙珙 (sometimes also referred to as Meng Gong 孟珙) Mengda beilu 蒙韃備錄 "A refined [report] of the Mongolian Tartars" is an eye-witnesses report of the Mongols' beginning conquest of the Jin empire 金 (1115-1234). Zhao himself had traveled north where he met Prince Mukhali (Chinese: Muhuali 木華黎) attacking the northern Jin capital of Yanjing 燕京 (modern Beijing). Yet Zhao's book is not a pure event history but a full and comprehensive account of the social, administrative and economic system of the early Mongol empire, and of north China at that time in general.
The oldest extant version is to be found in the collectaneum Shuofu 說郛, from which the early Republican scholar Wang Guowei 王國維 made his commented edition Mengda beilu jianzheng 蒙韃備錄箋證. An older commentary has been written by the Qing period 清 (1644-1911) scholar Cao Yuanzhong 曹元忠.
