The Unity Square of Chongqing University was originally not called Unity Square, but called the big playground, and was named Unity Square to commemorate the revolution. Unity Square is located in front of the main teaching building and management building of Chongqing University (pictured), with the concept wall of Bell Tower Square in front. It consists of a standard playground, a concrete basketball court, a volleyball court and a badminton court. The opening ceremony of the annual sports meeting in the old campus of Chongqing University was held here.
