In 1928, Nakano Michiomi returned to Manchuria, having enlisted in the army and having joined the Black Dragon Society. To facilitate his covert reconnaissance activities, he was posted in a Taoist school headed by Chen Lian, a priest who was also the master of Báilián Quán (白蓮門拳
Byakurenmon-ken). This was Nakano's first experience with Chinese
quan fa; he learned Báilián Quán under Chen while carrying out his assignment of making military maps and conducting geographic surveys throughout China. Later on, Chen introduced him to Wen Taizong, grandmaster of Yihe Quán (義和門拳
Giwamon-ken). Wen would take in Nakano as his student, training him for many years. In 1936 Wen formally passed his title of grandmaster of Yihe Quán to Nakano, at the
Mount Song Shaolin Monastery, at
Henan province. This version of events is contested by martial arts historians such as
Donn Draeger, who argues that, "[f]or Nakano to suggest that he, a foreigner, could succeed to a position of leadership over a Chinese martial arts tradition is to deliberately ignore Chinese tradition and to insult the intelligence of those whom he would have believe his claim". Donn Draeger also mentions a court case in which the Shaolin Temple made a case against Shorinji Kempo, but to which no relevant court documents or evidence can be found or have surfaced. In the final days of the Second World War, the Soviet Union broke its
neutrality pact with Japan, and declared war. On 9 August 1945, the Soviets
invaded Manchuria, and overran the Japanese in 11 days. The aftermath was appalling; Japanese casualties were tenfold to that of the Soviets's; wounded Japanese soldiers were left behind to die while the army retreated; and many Japanese civilians committed mass suicide. Sō was living in Manchuria during the Soviet invasion; he would witness such atrocities. He managed to escape to Japan with the help of his friends in Chinese secret societies, finally being repatriated in 1946. ==Establishment of Shōrinji Kempō and later life==
