During the process of mothers’ social role implementation, if mothers can’t satisfy themselves and others’ expectaction, they will have much negative emotion.and can’t develop full function of motherhood. This study indicates these messages about motherhood: motherhood’s priority, family harmony and ethnic prejudice. In light of these concerns, this paper suggests three implica tions for social work practice including: to construct the motherhood be “ multiple meaning”; to develop “the negotiation family harmony relationship”; to accumulate “the cultural assets”.
