In the summer of 1952 cadres of the Chinese Communist Party coerced the leaders of the Oroqen to give up their "superstitions" and abandon any religious practices. These tribal leaders, Chuonnasuan (Meng Jin Fu) and Zhao Li Ben, were also powerful shamans. The special community ritual to "send away the spirits" and beg them not to return was held over three nights in Baiyinna and in Shibazhan.
