IMO its not about the money but its about her game. Even though she won the China open I still don't think she has come back to her old self yet. She is still having some issues, mentally. She needs to reinvent herself add new strokes, think on the fly, re-strategize mid-game which the Chinese players do so well. She is not innately talented but its her hard work, focus and determination that has earned her the titles. Top level badminton is gruelling and she is feeling some pressure to keep up as almost everyone has read her game in and out. Mental and physical fatigue is taking over. Unless she re-invents she cannot get past that final barrier of top 2 or in other words the 'Chinese Wall'. She is suffering from the Chinese Syndrome. When she won China open, she said she was happy winning the tittle beating three Chinese on the way. As we know, none of the three are in top 10 and none of the are seeded. And yet she feels happy about beating them. This tells a lot about her current mindset.
