It is better to go to Shangdi Software Park for a run. Roads are being built along the subway near the city, and the dust is very heavy. There are no traffic lights around the software park, and there are not many cars before 8: 00 in the morning, so there is no need to suck the tail gas. Or it's best to run indoors and have a gym. The park in the south exit of Shangdi is too small. Not suitable for running
