Jiangshi jiaxun 蔣氏家訓 "Master Jiang's family instructions" is a book on Confucian family management written during the Qing period 清 (1644-1911) by Jiang Yi 蔣伊 (1631-1687), courtesy name Weigong 渭公, style Xintian 莘田, from Changshu 常熟, Jiangsu.
The text is written as an exhortation to Jiang's sons, with the instruction not to despise the poor and distressed and not to exploit peasants by demanding exorbitant rents. Instead, it was essential to study the writings of the ancients thinkers and financially support those who cannot buy books. In times of famine, the utmost duty of a scholar-official was to help the hungry. When choosing a son-in-law, the family head had to look for the reputation and the rank of the family as well as the official ranks of its members. When selecting a daughter-in-law, the virtue of her parents was decisive. Jiang Yi said that women becoming widows under the age of 30 sui might be allowed to marry again.
The Jiangshi jiaxun is included in the series Zeguzhai chongchao 澤古齋重鈔 and Congshu jicheng chubian 叢書集成初編.
