After a month of preparation, “Breakthrough”, the summer program led by Youth Committee (YC) volunteers, was successfully held in CUHK on 24 July. 34 participants and 11 Organising Committee members (OCs) were involved. 11 OCs collaborated to organize different parts of the program, including program design, promotion and recruitment, preparation of game materials, as well as site-visit. Despite encountering difficulties, OCs managed to solve different problems and practicality issues by active communications. On that day, the program began at University Station, where participants got acquainted with each other through ice-breaking games. Then, they were divided into four groups playing individual and joint group games in campus checkpoints like Weiyuan Lake. This fun and unforgettable program was rounded up by sharing and reflection. Both the OCs and participants understood the importance of teamwork and communication, and most importantly, made a breakthrough.
