Jiang Tianyi, whose courtesy name was Wen Shi and who was from Tongcheng, lost his father at an early age and served his mother with great filial piety. He was straightforward by nature and valued righteousness. During the Chongzhen period of the Ming Dynasty, when bandits invaded Tongcheng, Jiang Tianyi led the local villagers to resist them, leading from the front and killing many enemies. Later, he was appointed as a游击 general (a military rank) for his achievements but declined the position. After the Qing army entered the Pass, Jiang Tianyi chose to retire from public life and spent his time writing poetry and drinking wine. On his deathbed, he instructed his son: "All my actions throughout my life were done out of loyalty to the country and service to the people; you should take this as your guiding principle."
