Why would anyone hate Lin Dan? He plays well and he never do anything really bad both on and off the court. He never act rudely arrogant against his opponents during a game, he never shout like crazy whenever he wins a point, he never blames losses on injuries, I have not heard him sign autograph with an expressionless face or refused autographs without a reason, he never tell people "see you at world championship" all the time, he didn't have a lot of girlfriends and play around with women, and hey, he didn't even marry the daughter of some rich and powerful man!
All he did was quietly play his game and became world number 1. He's definitely one of the last to be hated.
Despite that, I hope LCW win. The guy deserves more titles for his hardwork.
