The largest one is Daesun Jinrihoe, which originates from Jo Jeongsan (1895-1958), who was not a direct disciple of Gang Il-sun but claimed to have received a revelation from him in 1917, eight years after Gang Il-sun's death. Jo Jeongsan's followers claim, however, that in 1909 Gang Il-sun saw a train passing, which had Jo Jeongsan, then a teenager, aboard with his family, heading to Bongcheon, Manchuria, to live in exile there, and stated: “A man can do anything at the age of 15 if he is able to take his identification tag ("hopae") with him.” Jo Jeongsan's disciples later claimed that these words amounted to an endorsement by Gang Il-sun of Jo Jeongsan as his successor. Gang's only daughter, Sun-Im (1904-1959), originally accepted Jo but later established her own branch, known as Jeung San Beob Jong Gyo, which is headquartered in Korea's North Jeolla province, and after protracted litigation with other branches obtained the mortal remains of Kang, which are currently at its headquarters.
