Chinese shuttler Lin Dan released his autobiography Until the End of the World on the same day he won the gold medal at the London Olympics, while Malaysian finalist Lee Chong Wei, whom Lin beat to take the gold, published his autobiography, Dare to Be a Champion, late last year.

The books' titles hint at the reality that the pair's rivalry will likely continue.

The recently crowned Chinese champion "Super Dan" is ready to fight at the next Games in Rio, especially after he heard Lee will extend his quest to claim Olympic gold to 2016.
