This study aims to understand how mother's "explicit and implicit maternal love" affect children's "perceptions of maternal love". We interviewed 8 mothers and their paired adolescent children. A life chart was used to record the levels of implicit maternal devotion, explicit maternal devotion, and maternal love perception. The thematic analysis of qualitative method involving an inductive orientation was employed. This study categorized two types of implicit maternal love: "rich and high" and "continual increase", and two type of affectional interactions between explicit maternal love and children's perceptions of maternal love: one is "busy mothers and ignorant children", the other is "difficult mothers and thoughtful children". Overall, We found that explicit maternal love exerts a greater effect on children's perceptions of maternal love than does implicit maternal love. Mothers of difference marital situation will affect the explicit maternal love, and thus affect the children's perceptions: busy mothers will deliberately reduce the explicit maternal love, children's perceptions of maternal love will be less because of feeling mother's favoritism, beating and forcing, however, difficult mothers will try to compensate the children for a sense of owing children, the mother's special situation seems to make children more precocious, better ability to reflect, better, perceptions of maternal love. Therefore, positive explicit maternal love actions, and reflective family education courses are encouraged by this study in school age and adolescence.
