Li Chang Yen is both a creature of sinister Orientalism and an echo of an earlier literary character: Fu Manchu by Sax Rohmer. The character was described as "the greatest genius which the powers of evil have put on the Earth for centuries", the foe of the British Empire and British civilization in general. The character combined great cruelty with advanced scientific research. In The Mystery of Dr. Fu-Manchu (1913), the eponymous character is presented as a figure behind Anti-Western actions in British Hong Kong and Chinese Turkestan. He is striking against Western politicians and administrators who are aware of the secret geopolitical importance of Tonkin, Mongolia, and Tibet, using these areas as a keyhole to the gate of the Indian Empire.
