On the early morning of July 26, people crowded around a white drone beside a pond in Gangyuan Village, Shaxi Town. The drone is used to investigate the vacated shacks and fields for garbage and ensure that there are no neglected corners in the beautiful countryside.

"The drone compiles data of a 5-square-kilometer field within only 2 hours, the same as a 2-day workload of a staff member." A third-party project manager praised the efficiency and precision of the drone with omnidirectional vision.

Since 2020, Zhongshan has launched a campaign to promote preservation of a beautiful countryside. As of June 28 this year, Zhongshan has demolished and renovated 24,501 shacks, and disposed of 18,216 tons of garbage, substantially improving the environment of the countryside.
