The Jianzhuke Shu (simplified Chinese: 谏逐客书; traditional Chinese: 諫逐客書; pinyin: Jiànzhúkè Shū; lit. 'Petition against the Expulsion of Guests') was a petition to Ying Zheng, King of Qin, written by Li Si in 243 BC. Written in response to an order to expel all officers serving in the State of Qin who were not born in Qin, it successfully persuaded Ying Zheng to rescind the expulsion order, and also began Li Si's career as a leading politician in Qin.
