It is a story of 24 pages picture book, which is about the footstep of time. It is based on my real feeling. When I was a kid, I felt time passes slowly, wanted to grow up quickly. However, when I became an adult, I felt time passes faster than before and I wished time can come back. The story tells us that time is not controllable. I don't want people to get anxious about the speed of time. The story tells a kid Amy who wanted to grow up quickly to do some solutions. In this story, stars represent time. Amy not only moved the hands on the clock tower, but also picked up the stars to make time pass faster. Also, the stars were collected in a box. However, when she quickly became an adult, she suddenly regretted. She thought of her box with stars and wanted to add more time, but all the stars disappeared. It turns out that time is like a river flowing forwards forever and is uncontrollable. We are supposed to know time is value.
