Having quit her job because of all the frustrations in the workplace, the girl Yating went to work as a volunteer teacher in a village called Qingmuta to get her happiness back. The poetic scenery, the honest villagers and the children with totally different characters there gradually lightened the gloom in her heart. One day, Yating happened to discover that her mom had also taught in village when she was young and the village was also named Qingmuta. Growing up together with the children, Yating began to talk and share more with her mom. As time went by, she finally got out of the “black hole” in her dream and found the goal and direction for her future.
