Nian An, 14, and Nian He, 10, once had a happy home in a remote town. Then one blow of fate followed another: their mother disappeared without a trace, and their father died of illness. Their once-happy family was shattered in an instant.
With no one to rely on, the siblings left their hometown for the big city, hoping to find their mother and rebuild their home. When they first arrived, they had nowhere to live and suffered from hunger and cold. Nian An did grueling labor at a construction site, enduring the foreman's constant harassment. At school, Nian He was isolated and bullied by classmates because her family was poor, but both siblings gritted their teeth and carried on in silence.
Fortunately, Nian An's hard work caught an engineer's attention, giving him the chance to learn about construction and gradually improve their lives. But Nian He was then ostracized for not being able to afford a costume for a school performance, so Nian An took odd jobs to make her dream come true. Later, Nian An got the opportunity to pursue further studies, and Nian He supported him wholeheartedly. Their search for their mother was full of twists and turns, and hope was dashed again and again. Just as they were nearly ready to give up, the police brought news: their mother had lost her memory after an accident and wandered away, but after recovering her memories, she had started looking for them.
At last, the family was reunited. Nian An used his skills to get a job at a well-known company, their mother found work, and Nian He was happy at her new school. They had struggled through the darkness, but a glimmer of light led them out of hardship and into a bright new life.
