"During the battle between the father and the son on the rink, their situations are gradually reversed. After that, they can better understand each other," Liu says.
A viewer on the review site Douban comments: "The documentary reveals the struggles young parents face in educating their children and also shows how the different educational approaches of parents can affect children's self-confidence and behavior. It's a good one for parents and their children to watch together."
Liu's daughter is already 4 years old. Has he found the answers to his questions after the documentary's production? He says: "Not really. What I'm pretty sure about is that if one day my daughter comes to tell me about her dream and shows strong determination, I will help her to examine the dream and support her choice."
