For instance, at Hua's stop in Anhui province's Dongdao village, viewers see the villagers engage in discussions and the resolution of village affairs during a meeting. All residents are encouraged to attend and freely express their opinions, with the option to raise their hand to support a particular motion. The village's basic infrastructure, including the gatehouse, streetlights and basketball court, was all constructed as a result of this democratic process.

"Unified action by villagers can create tremendous momentum. When their hearts are invested, their efforts will bear fruit. By taking the initiative, they can bring positive changes to their community," says Li Kewen, director of Dongdao's village committee.

In Wanjian village, Anhui province, viewers see how the ancient settlement, which was founded in the Ming Dynasty (1368-1644), has been transformed into a tourist attraction boasting renovated residential houses, a library, a museum, an activity center for elders and a tourist service center.

"The villagers were truly happy, making it easy for us to capture the sincere smiles on their faces," recalls Sun.

Additionally, the documentary also casts light on food safety measures taken by Huzhou, Zhejiang province; the urban traffic management system in Wuhan, Hubei province; the ecological protection efforts made by Sichuan province and the construction of 5G base stations in Lhasa, Tibet.
