Third Line Nostalgia: Children of the Mountain Valley

In 1970, idealism meets isolation when urban families abandon city life to answer their nation's call. Deep in the mountains of western Liaoning, they carve out existence in a forgotten valley—building factories, schools, and dreams from nothing. But it's their children who truly belong to this wild landscape, growing up between two worlds: the fading memories of metropolitan comfort and the raw beauty of mountain survival. A tender chronicle of youth, sacrifice, and the bonds forged in China's most turbulent era.
