Bronze and sunflower

"Sunflower is lonely when she moves to the countryside, until she meets Bronze, a young boy who is unable to speak and is ostracised by the other boys. Bronze's family agree to take the orphan girl in, but life is hard, and they can barely afford to feed themselves. Set at the time of the Cultural Revolution in China."@en
"When Sunflower, a young city girl, moves to the countryside, she grows to love the reed marsh lands - the endlessly flowing river, the friendly buffalo with their strong backs and shiny round heads, the sky that stretches on and on in its vastness. However, the days are long, and the little girl is lonely. Then she meets Bronze, who, unable to speak, is ostracised by the other village boys. Soon the pair are inseparable, and when Bronze's family agree to take Sunflower in, it seems that fate has brought him the sister he has always longed for. But life in Damaidi is hard, and Bronze's family can barely afford to feed themselves. Will the city girl be able to stay in this place where she has finally found happiness?"
