Dongzhengji 東征集 "All about the campaign against the east" is a history of the suppression of Zhu Yigui's 朱一貴 rebellion in Taiwan in 1721 written by the Qing period 清 (1644-1911) writer and politician Lan Dingyuan 藍鼎元 (1680-1733). The 6-juan long book was written on the base of Lan's personal experience while he accompanied the campaign that was commanded by his relative Lan Tingzhen 藍廷珍 (1664-1730). The book therefore includes a lot of quotations from original documents passing the table of the headquarters. The last chapter includes general information about the island of Taiwan and some individual officials that lost their lives during the war.
The book was revised and printed in 1732. For the series Siku quanshu 四庫全書, the Dongzhengji was included as an appendix to another book of Lan Dingyuan called Ping Tai jilüe 平臺紀略.
