Jiangnan yuzai 江南餘載 "Remaining records of Southern China" is a history of southern China during the 10th century written by an unknown author during the Song period 宋 (960-1279). It is a condension of the histories written by Wang Ju 王舉, Lu Zhen 路振 (1111-1187), Cheng Pengnian 陳彭年 (961-1017) and Yang Yi 楊億 (974-1020) that were compiled as extensions of the Jiangnanlu 江南錄 (see Jiangnan bielu 江南別錄).
The received book is a product by Zheng Wenbao 鄭文寳 (953-1013) who brought these different versions together into one book. The Jiangnan yuzai must be seen as a draft to his 3-juan long treatise Jiangbiaozhi 江表志. The Jiangnan yuzai could be reconstructed form fragments surviving in the Ming-period 明 (1368-1644) encyclopaedia Yongle dadian 永樂大典.
