The idea of sustainable development proliferated in our neighbourhood Siu Sai Wan community with the support of the Council of Sustainable Development. On 7 July 2013, after diverse performances of dancers, choirs and orchestras, ten booths were set up to transmit different ideas and concepts related to sustainable development.  Involving over 100 students and 40 teachers, the Carnival came with an enthusiastic participation of over 200 visitors and a memorable end.
