The Tong of the Black Scorpion was a fanatical cult convinced that he would return one day and rule the world.
51st century time traveller Magnus Greel was believed to be Weng-Chiang by Li H'sen Chang when he found him, and thus Greel gained control over the cult. (TV: The Talons of Weng-Chiang) Descendants of the Tong soldiers who believed Greel to be Weng-Chiang were told stories of the god's anger. (PROSE: The Shadow of Weng-Chiang)
