Fan_Shengzhi_shu
Fan Shengzhi shu ("Fan Shengzhi's book" or "Fan Shengzhi's manual") was a Chinese agricultural text from the Han dynasty, written by Fan Shengzhi in the first century BC. The book was lost in the 11th- or 12th-century Song dynasty, possibly during the Jurchen invasion. Several fragments of the text have survived as quotations in other books including Qimin Yaoshu, Beitang Shuchao , Yiwen Leiju, and Taiping Yulan.
