Congcong and the Magical Jigsaw Puzzle

Congcong is a clever, brave, and kind child. When summer vacation arrived, his dad rewarded him with an Olympic jigsaw puzzle, and Congcong was overjoyed. But while putting the puzzle together, careless Congcong accidentally spilled ink on it. That was bad news for the Olympic spirits living in the puzzle's "Olympic Spirit City": they came down with strange illnesses. The sacred flame atop the Olympic Flame Spirit's head was about to go out. Grandpa Five Rings had lost his memories of China's participation in the Olympics. The Table Tennis Spirit refused to admit that the Tennis Spirit was his own brother... Can Congcong pilot the time machine and help Grandpa recover his memories, discover the origins of table tennis, and do all sorts of other things? Set off, Congcong! You can do it!
