I'm submitting a photo called "Stone City Wall Park". Due to Coronavirus, China was shut down for a while, and all production activities were stopped. One day, I went out with my camera, and found Stone City Wall Park. Stone City is a famous ancient town in the six dynasties of Nanjing in Jiangsu Province of China, and there is a park built around its ruins. Before it had been quite quiet , however, because kids didn't go to school, and adults didn't go to work any more, they would come to the park to have fun or relax, thus I have taken some photos and I'd like to share it with the world.
