The Hmong Protestants have changed their traditional customs as worshiping the gods, devils, offerings, healing as well as relationships of family, family line, community. Protestantism propagated and developed in the Hmong community in northwestern Vietnam has contributed to the eradication of many backward customs that have existed for thousands of generations, but on the other hand, it also disappeared many customs and practices of the Hmong people here. The existence and development of Protestantism in the Northwest has caused cultural change in many ways, in which the most obvious manifestation is the change of morality, lifestyle; family institution; relationships of family, ethnic groups, communities and customs, beliefs, festivals. http://pubs.sciepub.com/wjssh/4/3/2/wjssh-4-3-2.pdf cultural change Hmong protestants Northwest in Vietnam
