Sorry, been finishing up with my Uni finals
DeVrie is correct. But the easiest way to understand what each "religion" is, is to mouse-over the "religion" trait for characters. But anyways, here is the list of "religions":
Revive the Dynasty (Revival): The people want to revive the Han Dynasty and restore it to its former glory.
Birth of a Dynasty (Dynastic Change): The people wish for the Han dynasty be replaced by a new and vigorous Dynasty.
Isolationist: The people desire internal security and peace free of interference from all outside influences.
Factionism: The people want to form an independent factional state free from central administration.
Foreign Culture: The people dislike Han customs and want a new and foreign culture to follow.
Daoism: The people are inclining towards the extremely metaphysical teachings of Lao Zi.
Daoist Revolution: The people believe that the old order has collapsed, and that a new Heaven, faith and order will take its place to lead the people to the era of Great Peace.
