This book "Lang Lang Playing With Flying Keys" is written by Lang Lang, a famous pianist, Micheal French,who have already published twenty books,and Danlel Barenboim ,who takes the picture of this book. This is a 208 pages biography book, written about a famous pianist who have hardworking to become a world famous pianist. But on the way to be famous, there are still a lot of unhappy stuff like Lang Lang is very angry about his dad, by making him doing the stuff that he didn't want to do and his dad didn't want him to play toys. But Lang Lang is still getting in to playing piano. The main lesson Lang Lang learned is that don't ever give up on the thing that are hard or maybe you can't get done so easy because if not then it will be more harder than it is before. For example, when Lang Lang stop playing just because his dad is being mean to him so Lang Lang just stop playing. After three mouth when he start playing again, he almost for got all the thing he learned. So that's the most important thing he learned. I would recommend this book because first this book is good, it help more people knowing that being a superstar is not a easy thing, they have to be hardworking to became a superstar and don't give up on some thing that is hard. And the one unanswered question to Lang Lang is "if your dad didn't make you play piano then what are you going to do, still playing piano or not?"
