To celebrate the 70th anniversary of the Hong Kong Mental Health Association, the Lee Cheng Uk Estate collaborated with the So Uk Estate to organize the “Deep” Joy Carnival and Open Day. Our school was invited to serve as a team of student volunteers for the event, working with various non-profit organizations to prepare booth games, performances, art workshops, and unique experiences related to the estates. The event aimed to convey the message of “Four Joys of Mental Health,” which include: “Joy of Eating,” “Joy of Movement,” “Joy of Sleeping,” and “Joy of Loving,” promoting the message of holistic well-being to the public.
