Du Gongbu nianpu 杜工部年譜 "Annalistic Biography of Minister of Works Du Fu", also called Du Gongbu caotang shi nianpu 杜工部草堂詩年譜 is an annalistic biography (nianpu 年譜) of the Tang-period 唐 (618-907) poet and politican Du Fu 杜甫 (712-770), who was Minister of Works (gongbu 工部).
The book was written by the Song-period 宋 (960-1279) scholar Zhao Zili 趙子櫟 (died 1137), courtesy name Mengshou 夢授. He hailed from Tianshui 天水 (modern Tianshui, Gansu) and was a descendant of Emperor Taizu 宋太祖 (r. 960-975), the founder of the dynasty. He obtained his jinshi degree in 1091 and was appointed auxiliary academician (zhixueshi 直學士) in the Baowen Hall 寶文閣.
Zhao Zili's book is only one of a series of biographies of Du Fu that were written during the Song period, such as those of Lü Dafang 呂大防 (1027-1097), Cai Xingzong 蔡興宗, Lu Yin 魯訔, Ji Minfu 計敏夫, Huang He 黃鶴, Lü Ruo 呂若, Bao Biao 鮑彪 (jinshi degree 1128), Liang Quandao 梁權道, Wu Renjie 吳仁杰 (jinshi degree 1178) or Xu Zhai 徐宅.
The most important scholarly finding of Zhao Zili's book is the date of Du Fu's birth and death that he fixed as 712 and 770, and not, as formerly done, 713 and 771.
