Feng Hongduo (馮弘鐸) was a warlord late in the Chinese Tang Dynasty, who controlled the Sheng Prefecture (昇州, in modern Nanjing, Jiangsu) region from 893 to 902. Background Feng Hongduo was originally from Lianshui (漣水, in modern Huai'an, Jiangsu), and he served as an officer at Ganhua Circuit (感化, headquartered in modern Xuzhou, Jiangsu), which Lianshui belonged to. Once, when Feng was accused of impropriety by circuit administrators, fellow officer Zhang Xiong, who was also from Lianshui, spoke on his behalf, and Zhang's doing so caused Ganhua's military governor (Jiedushi) Shi Pu to suspect both of them.
