Sunshine Post Project provides protection, psychological consultation and family education guidance for left-behind children by setting up post offices, aiming at helping them grow up healthily. Sunshine Station is supported by the central special lottery public welfare fund, and is committed to building a demonstration project of caring for left-behind children through practical exploration in various places. The establishment and operation of the post station requires the joint efforts of women's federations at all levels, government departments, social organizations and volunteers to provide all-round support and services.
