曽国藩
The concern with the "self-strengthening" of China was expressed by Feng Guifen (1809–1874) in a series of essays presented by him to Zeng Guofan in 1861. Feng obtained expertise in warfare commanding a volunteer corps in Qing government's campaign against the Taiping rebels. In 1860 he moved to Shanghai, where he was much impressed by Western military technology.
