和好教
Huỳnh Phú Sổ faced a great deal of trouble when he began to spread the ideas of his religion, a large part of which was Vietnamese nationalism, a dangerous idea at that time of French colonial rule. He was put in an asylum because of his preaching, but supposedly converted his doctor to the Hòa Hảo belief. As the popularity of Hòa Hảo grew, Huỳnh Phú Sổ made a series of prophecies about the political future of Vietnam. He said that the "true king" would return to lead Vietnam to freedom and prosperity, which caused most Hòa Hảo to support the Nguyễn pretender: Marquis Cường Để, living abroad in Japan.
