At Tsinghua, Tsiang became the head of the History Department, where he edited and published a number of works on Chinese history and edited the English-language journal "Chinese Social and Political Science Review". Using newly-opened Qing dynasty archives and diplomatic publications, Tsiang argued that China should adopt Western approaches if it wanted to score diplomatic victories. Tsiang blamed China's unequal treatment by Western powers after the First Opium War (1839–42) on Chinese unequal treatment of Western powers before the war. During his tenure at Tsinghua, he mentored a number of historians in the study of Qing history, including John K. Fairbank.
