Headquarter

The whole Sai Kung district was so desolate (荒蕪的) and well covered by the guerrillas that they kept their radio transmitter and their mobile headquarters in either Chek Keng or Cheung Sheung for a long period. Both of these locations are neighboring villages accessible within walking distance. But both could only be reached through steep climbs through village paths. By 1943, the East River Column had an elaborate and well-organized structure. In addition to the full-time soldiers who were organized into six different duis with a total strength of about 5000, the paramilitary side had departments with duties such as logistics, intelligence, minyun, hearts and minds work, newspapers, radio station, propaganda, signals, reconnaissance, VIP protection, foreign liaison, medicine and field hospital and training.
