Zhengnanlu 征南錄 "Southern Expedition", also called Sun Weimin zhengnan lu 孫威敏征南錄 "Sun Weimin's southern expedition", is a report of a military campaign compiled by the Song-period 宋 (960-1279) scholar Teng Yuanfa 滕元發 (1020-1090).
The short book is a chronicle of the suppression of Nong Zhigao's 儂智高 rebellion in 1052 that was lead by pacification commissioner (anfushi 安撫使) Sun Mian 孫沔 (996-1066) and pacification commissioner (xuanfushi 宣撫使) Di Qing 狄青 (1008-1057). After the successful defeat of the rebels, the court highly honorated Di Qing and neglected the role Sun Mian had played in that campaign. Teng Yuanfa, who took personally part in the expedition and was a kind of advisor to Sun, had experienced the important role the latter had played in the war. He therefore compiled this book in order to propagate the military virtues of Sun Mian.
Weimin 威敏 "Severe-Clever" is the posthumous honorific title of Sun Mian. The book can serve as a source of detailed information and a supplement to the official dynastic history Songshi 宋史. It is included in the series Siku quanshu 四庫全書 and Xu jinhua congshu 續金華叢書.
