Abstract: Traditional social association theory takes lineage,territorial bond,professional tie,and interest bond as the main content of the social combination;and the differentiation order,from the individual’s blood kinship to distant relatives and non-relatives,forms the foundation of social association,the process of social association of those individuals with non-blood and differential relations being little discussed.The local concept of “ban” is a fuzzy spatial framework for the Lisu people to deal with those of non-family members,including non-blood friends,acquaintances and strangers.This paper,by investigating and illustrating the local concept of “ban”,analyzes and presents the process of social association of those individuals with non-blood relation and differentials.Also,it provides data different from traditional social association theory and differential pattern for discussion,conversation and supplementation.

Key words:  , Lisu people, &ldquo, Ban&rdquo, individual, social association
