Liuchao tongjian boyi 六朝通鑒博議

Liuchao tongjian boyi 六朝通鑒博議 (六朝通鑑博議) "Extensive deliberations about the Comprehensive Mirror of the Six Dynasties" is a historical critique of the Six Dynasties period 六朝 (222~589) written by the Song period 宋 (960-1279) scholar Li Tao 李燾 (1115-1184), author of the Xu zizhi tongjian changbian 續資治通鑒長編.

In the 10-juan long Liuchao tongjian boyi Li Tao discusses mainly military matters of the Three Empires 三國 (220-280), the Jin 晉 (265-420) and the Southern and Northern Dynasties 南北朝 (300~600) periods. A core theme of his discussions is the southward transferral of the Jin court, and the foundation of the Liu-Song dynasty 劉宋 (420-479), the first of the Southern Dynasties 南朝 (420~589). The fight of the Liu-Song empire against the non-Chinese state of the Northern Wei 北魏 (386-534) functions as a mirror of the defence of the Southern Song dynasty 南宋 (1127-1279), under which Li Tao lived, against the Jin empire 金 (1115-1234) in the north. The Liuchao tongjian boyi is therefore also a direct advice for Emperor Xiaozong 宋孝宗 (r. 1162-1189) for an effectful government.

The book has survived as a manuscript in the Zhenqi Studio 振綺堂 and is included in the imperial series Siku quanshu 四庫全書.
