When the clouds sing, you come to my heart. Inspired by the ordinary and touching love story of Bandu's guardian and his wife, Bandu's yearning for his lover was deeply expounded, which was touching.
The background story is that a man named Bandu is guarding 58,000 mu of Populus euphratica forest in Ejina, Inner Mongolia, China. For the survival of Populus euphratica, Ban kept digging wells to find water. Every morning when it is windy, Bandu's wife will get up and simmer a pot of warm milk tea and cook a full meal.
