Green Gang
During the Sino-Japanese War, NBIS had orchestrated the assassinations of several key Japanese enemy military and government personnel. Between 1937-41, the "Juntong", working together with the Green Gang triad, carried out 150 assassinations of Chinese collaborators and 40 Japanese officers in Shanghai alone. The "Juntong" favored assassinating Chinese collaborators over the Japanese partly because they were easier to kill as the Japanese tended to stick to certain enclaves, but mostly to prevent the Japanese from imposing any sort of ordered government in parts of China they had occupied. Japan had occupied vast sections of China inhabited by millions of people requiring hundreds of thousands of civil servants to administer while the number of Japanese who were fluent in Mandarin or Cantonese was limited, and to a very large extent the Japanese depended upon Chinese collaborators to administer China for them. Zhang Xiaolin, a leading member of the Green Gang who went over to the Japanese in 1937 was gunned down by a "Juntong" assassin. In October 1938, Tang Shaoyi, a former prime minister of the Republic of China who had agreed to serve the Japanese was killed at his home when a "Juntong" assassin posing as an antique dealer used the antique axe he was showing to Tang to smash in his head. As the Japanese had no idea of who the "Juntong" assassins were, they resorted to executing at random innocent people who had nothing to do with the assassinations.
