Green Gang
Tang Jiyao had a cousin, Tang Jiyu, who was also a general. Tang Jiyao sought to use propaganda to gain publicity for himself on the national stage in China. He smuggled confiscated opium to Shanghai, but the local Green Gang informed the British authorities and much of the opium ended up on the black market. Tang Jiyu avoided Shanghai during the trial against officials involved in the opium deal in 1916.
