In the northwest corner of Ritan Park, there is the tomb of martyr Ma Jun and the memorial room, which was also listed as a patriotic education base in Beijing in 2001. Every year at the spring equinox, the park hosts the Chaoyang District Folk Culture Festival, and only then is it possible to enter the altar, and the altar is closed otherwise. At the same time, there are folk performances, Beijing intangible cultural heritage exhibitions, eating sun cakes, erecting eggs and other activities. Now the park is free for the public, and a place for leisure and fitness.
