Jiran wanwu lu 計然萬物錄 "Jiran's records of the ten thousand things" was an agricultural treatise attributed to Jiran 計然, personal name Xin Jian 辛銒, and better known as the philosopher Wenzi 文子 who lived during the Warring States period 戰國 (5th cent.-221 BCE).
The book Wanwulu was certainly not compiled by Jiran himself but is of a later date. It describes the production of various objects. Fragments of it were compiled by the Qing-period 清 (1644-1911) scholar Mao Panlin 茆泮林 (d. 1845). They are to be found in the series Congshu jicheng chubian 叢書集成初編.
