The three religions here are not the Confucianism, Buddhism and Taoism that we often talk about,
But the three religions in the folklore are the Hung Gar Sect, the Ching Gar Sect and the White Lotus Sect.
The Ching Clan and the Hongmen
Although the Ching Clan and the Hongmen have quite a lot of origins, but because of the practice of Zen system, so with the Hongmen in the mutual brotherhood of different, Ching Clan organization is to worship the master to join the gang, the congregation of the master and disciple to the same name, the worship of the master and disciple, as the father and the son. Qing Gang organization is more strict than the Hongmen, the rules are more complex, so also more secret. Therefore, there is a saying: "Qing gang a line, Hongmen a large area".
Tend to the nature of the guilds of the Qing gang did not emphasize as the Hongmen as anti-Qing Dynasty and restore the Ming Dynasty, but more or less agree with this idea, advocating "for the sake of heaven". Because the Qing gang did not actively engage in anti-Qing activities, so the Hongmen once as a traitor, strictly prohibit the Hongmen members to switch to the Qing gang, said "from the Qing to the Hong, red and colorful; from the Hong to the Qing, peeled skin." . However, in order to avoid conflict, the two factions are still called "Qing Hong family", the so-called "red flowers, green leaves, white lotus root (refers to the Hongmen, Qing Gang, White Lotus Sect), the three original is a family". Especially in the late Qing Dynasty, many of the Qing gang disciples also began to anti-Qing, the two factions gradually reduce hostility.
