Social science union is an interest group that arouses our fellow students' interest in social science. Social science is a major academic discipline, concerned with society and the relationships among individuals within society. The main social science subjects include economics, history, geography, political science and sociology. Our activities mainly focus on economics, history and geography as they are the DSE electives that many of our students have chosen. We hold activities like video-watching, fun day and inter-class competition such as inter-class paper recycling competition to apply social science in an interesting way, thus helping students develop interest in social science.
