Baobao and Beibei are twins and live in Nanjing. When they were three-and-a-half years old, their parents were laid off. To secure their the children's future, their parents choose for Baobao and Beibei to be gymnast, because the school sports coach had praised them. In order to train sports stars, amateur sports schools conduct cruel training on young children. Parents also have to obey the coach’s request and force their children to practice exercises. They believe that sports are a fair competition, and, as long as they are hard-hearted and push their children to the top, they will have bright prospects. Baobao and Beibei spent their childhood training like this. Their ideal is to participate in the Olympics, win gold medals for their country, and buy a house for their parents.
