(Rubik's cube is not only an educational toy, but also a teaching aid and sporting goods. As a competitive sport, playing Rubik's cube requires the cooperation of hands, eyes and brain. This fingertip competition can not only exercise children's hand and brain ability, but also enrich their after-school life. This is really interesting and a good thing worth promoting.)
