The purpose of this thesis is to study relationship system among Hmong peoples and relationship system of Sangha of monks in Buddhism, and compare relationship system of those two groups. The study revealed that   

The relationship system among Hmong peoples is a process of social organization by using belief, tradition, rites, and culture as the tool to make relationship among peoples in the group. Hmong peoples gave precedence to descent system mainly via the blood of father. To count relative relationship, it is done backward to father and grandfather respectively. So, the man was descended from father and the woman changed her surname to be the one of her husband after marriage. Therefore, all Hmong men with the same surname are brothers. Besides being a kind of blood system by being descended from father and mother and by marrying, it also was inherited via culture of relative identity created by leaders and rite leader. Establishment of relative relationship is to enlighten peoples in the society to support each other and have self-support, build unity, and control deviated behavior of members in the society to be in the (Imagined Community) and also strengthen unity of Hmong ethnic group.     

                      Relationship system of monks is in the frame of discipline as the provision of co-living of group members. The Sangha society had evolution consecutively, where expansion of number of members in the monk society is the main factor. When number of members in the monk organization was increased, the Buddha regulated more discipline as the rule and regulation for co-living orderly, supporting practice of members in the same direction, organizing relationship system according to basic structure of social gathering of human. Preliminarily, the Buddha regulated social rules with intention to have members in the Sangha had appropriate principle for living; study, earning living, administration, formal acts (Sangha Kamma) so that the monk would be educated to reach the Buddhism goal, where the discipline (Precept), code of practice and doctrine for practice are the principle for living. The social process of monk gave precedence to right of participation in activities and benefits of group thoroughly and equally, good feeling to one another, respecting one another, living with unanimity, order and tidiness, harmony, treating to one another with supporting mainly, physical, verbal, and thinking freedom. These are the social group plentiful with dharma in living.     

            From study on and comparison between relationship systems of those two groups, that is, Hmong peoples and Sangha in Buddhism, they revealed theoretical idea and practice method of relationship system of those two groups as follow: Those relationships systems of those two group had different social environment and culture and also different factor causing gathering and process of social structure, that is, the theoretical idea and practice method of Hmong peoples gave precedence to belief, customs, tradition, and rite via the process of inheriting from their ancestor as their own culture. The Sangha gave precedence to the provision of discipline as the rule and regulation for members in the group and tradition or culture for practice of the group. By the way, the goal of relationship system of those two group is to make peacefulness, brotherhood, and unity for all members in the society.
