'Interclass Green Christmas Competition' was held on 20th December, 2019. Students were encouraged to bring their own utensils for the Christmas party to help reducing waste production. They also did a great job in recycling useful materials after the party, for example, plastic food containers, plastic bottles, waste paper, and cans. At the end of the party, Civil Ambassadors went to each class to measure the amount of rubbish they produced in order to decide the winning classes.
