From Belgium, Jialai Wang maintains contact via smartphone and camera with her mother and grandmother in China. When her grandmother’s health deteriorates, Jialai returns to Shanghai, but when she arrives, her grandmother has already died, and she is left alone with her mother. A devout Buddhist, her mother seems to pay more attention to her daily prayers, Maoist past and dog Dongdong than she does to her daughter. She herself had been abandoned as a child by her own mother, when she divorced Jialai’s grandfather and moved to the city.
