Li Shuwen

Li Shuwen (Chinese: 李书文) (1864–1934) was a master practitioner of the Chinese martial art of Bajiquan. He was known as "God Spear Li" (神槍李). His prowess was said to be enough that he boasted that he did not have to strike the same opponent twice. He was a martial arts adviser of Fu Chen Sung, notably once fighting him to a draw. Li's students eventually became personal bodyguards for Mao Zedong, Chiang Kai-shek, and Henry Pu-Yi.

Li Shuwen is depicted as the character "Assassin" in the video game Fate/Extra. The Japanese manga "Kenji" depicted Li Shuwen according to numerous accounts from various sources, notably from Li Shuwen's last student Liu Yun Chao.
