A single screen can oversee ten thousand mu of farmland. A young agronomist returns to her hometown to dedicate herself to smart agriculture, helping villagers cultivate better lives in the fields of hope.

In the fourth episode, "Warmth in the Fields," set in 2035, Lin Xiaoxia, a reporter from China Women's News, walks into a vast smart farmland to revisit young agronomist Wang Xiaoning and look back on the youthful wish she wrote down in 2026.

Looking back in time, Wang Xiaoning once watched her parents toil in the fields year after year, often too busy to eat meals on time, enduring tremendous hardship. Deeply moved, she made a wish during the "Letter to My 2035 Self" activity, hoping that her future self would devote herself to smart agriculture, return to the land that raised her, and help the folks back home cultivate better days in the fields of hope.

As time flew to 2035, Wang Xiaoning fulfilled her dream of returning home to work the land and grew into a professional smart agronomist. Today's countryside has already taken on a completely new look. Relying on smart agricultural technologies such as remote sensing monitoring and intelligent agricultural machinery, farmland has achieved refined and intelligent cultivation, completely rewriting the traditional farming model of her parents' generation and freeing field labor from the hardship of bending over the yellow earth.

In the fields, Wang Xiaoning and Lin Xiaoxia meet a buyer who has come to negotiate business. In the past, everything depended on her parents' judgment, but now Wang Xiaoning stands on her own, fully handling agricultural product procurement matters and becoming a trusted agricultural backbone in the village.

When a neighboring farmland suddenly issues a crop condition warning and an irrigation valve malfunctions, Wang Xiaoning relies on the smart agriculture platform to remotely and quickly troubleshoot the problem and promptly resolve the drought affecting the fields, fully demonstrating the professionalism and sense of responsibility of a young new farmer.

From a childhood wish born of sympathy for her parents' hard work to the commitment of a young person dedicated to rural development and technological agriculture, Wang Xiaoning uses what she has learned to empower the local fields, injecting vibrant young energy into rural revitalization.

The warm exchange of roles between parents and daughter bears witness to the iterative upgrading of rural agriculture and continues the simple, everyday warmth of rural life.
