Dai Li
In 1938, the Special Works Department was expanded and took over the "Investigation and Statistics Bureau" to cope with the increasingly demanding tasks of intelligence operations. Dai Li was assigned as the "de facto" responsibility for running the unit. Dai's preference for recruiting on the basis of familial loyalties, where one sibling would recruit other siblings to the "Juntong" proved to be a weakness, when in 1938 a number of "Juntong" agents defected over to work for the "reformed" government of Wang Jingwei, pitting brother literally against brother.
