If you know the story of Mao's Last Dancer, then this story will seem rather boring. It is very similar in terms of the major plot points, but with a lot less detail and beauty in the written word.
I felt that the book does explore the emotional state of Jin Xing, but it barely scratches the surface of those emotions, which is quite a let down for the reader. It seems to gloss over a lot that happens in Jin's life at that time with little to no explanation of how Jin felt.
Each scene gave you but the briefest of glimpses of Jin's inner thoughts and feelings, I wanted so much more.
