"Hum..." Yesterday (June 11) at 9:30 am, a white drone flew over the north area of Yile new village, Wenyi West Road, Hangzhou.

Zhou Chao, the young man who controlled the drone through a tablet on his hand, observed and recorded the situation of the roofs.

This is a day-to-day routine for Yile new village to sent out drones to inspect whether the roofs were piled up in disorder since Hangzhou launched the "renovation of the urban environment and improvement of the city's appearance".

There are 456 households in Yile new village, including more than 300 in the north area and more than 100 in the south area.

"The north and south areas both are the range of drone patrol. Three times a week whenever the weather is good. Due to the battery limitation, each patrol will last for about half an hour," Zhou Chao introduced.

Villagers acknowledged that they were informed of what it was doing in the village when interviewed by the reporter.

"When the drone first conducted a patrol, it was hard for the villagers to accept it. Some of them didn't cooperate." Zhou Chao said that the management mode of Yile new village was later proved very effective. "Now it's almost impossible to see people leave the roof in disorder. If any, we'll make a phone call and villagers will do the cleaning."
