The Chee Kung Tong (Chinese: 致公堂; Jyutping: zi3 gung1 tong4), or Gee Kung Tong, was a Chinese secret society established in 1880 and holds an active presence still. In earlier years, the society has also been recognized as the "Chinese Masons" and has been identified under various names such as Hongmen (Chinese: 洪門), Hongshuntang (Chinese: 洪順堂), and Yixingtang (Chinese: 義興堂). The fraternity founded its headquarters in San Francisco in the United States.[1]
