Dai Li
The National Bureau of Investigation and Statistics (Military Commission), (NBIS or BIS) (), commonly known as Juntong (), was the military intelligence agency of the Republic of China before 1946. It was devoted to intelligence gathering and covert spying operation for purposes of national security and defense. It was originally headed by Dai Li, and after 1946 he was succeeded by Mao Renfeng. This bureau was largely superseded by the Military Intelligence Bureau under Ministry of National Defense in Taiwan today.
