“ The term “to shanghai” is used of a more serious offence. Literally meaning “to ship to Shanghai,” in China, it is applied to the drugging or rendering unconscious by violence or other means of persons, whether sailors or not, and shipping them to distant ports, in order fraudulently to obtain money in advance of wages, or for the sake of the premium paid for supplying crews. ”
