August 8, 2020 marked the 12th National Fitness Day in China. In that morning, the launch ceremony of the 2020 Zhongshan National Fitness Day and the Xijiang River Happy Swimming event was held in Nantou Town. Hundreds of swimmers and enthusiasts swam in the Xijiang River together to celebrate the sports festival in a special way.

The whole course of the swimming tour is 5km, with a resting point at 3km. During the course, unmanned aerial vehicles were used to track and photograph the whole process, and rescue boats and medical personnel were on standby. After about an hour of swimming, the participants arrived at the finish line one after another.

On the same day, nearly 100 public stadiums and gymnasiums in Zhongshan were opened to the public for free or at low fees. At the same time, a total of 500 free fitness coupons were issued to the public through a night run activity.
