The rationale of JCEs are “Children Rights” and “Children Participation”. We believe children’s opinions and willingness are fundamental elements of a child-friendly city. Children are part of our society and their opinions should be respected and considered. We here provide a platform for JCEs to organize and participate in different community affairs. Not only can they express their views on social issues, but also deeply understand and serve the needs of different groups of people. By encouraging children to participate and voice out, the society awareness and concern on “Children Rights” and “Children Participation” can be raised.
