In order to promote plant biodiversity and show students’ care to the elderly, the School’s Sustainable Development Team and Green Guru Team have organized an Elderly Service Program namely “Chinese Herbal Health Tea Workshop “with the Chinese YMCA Chai Wan Neighborhood Elderly Centre on 18 Jan 2020. Twenty elderly visited our Chinese Medicinal Herb Garden and Science and Sustainable Development Resource Center (SSDRC) at the Main Roof. Our Green Gurus took this chance to promote conservation of plant biodiversity through sharing tea culture with the elderly.
