Wo Shing Wo
The Wo Shing Wo branch in the Netherlands was founded and primarily operates in Rotterdam. In the 1970s, the group battled the 14K and Ah Kong for control of the heroin trade in Amsterdam. In addition to heroin trafficking, the group also operates gambling, prostitution, money laundering, loan sharking, robbery, extortion and human trafficking. The Wo Shing Wo has more recently also closely cooperated with the 14K.
