While moving and packing her belongings, Hui Hui found her grandfather's beloved black bear paperweight, who was also her best friend from childhood: A Mo. Although her grandfather always kept the paperweight in a glass cabinet, Hui Hui always took A Mo along as her playmate, whether it was during bath time, reading time, or hide-and-seek. It seemed as though A Mo had been a part of every moment of Hui Hui's childhood.
