It is difficult to argue with them (especially Western) when China pairs have thrown the match in the women double. But the problem is they might start to make any generalization and boo an innocent player. In order to establish your reputation, you just have to talk with the racket. Thousands of explanation or arguments will not convince them. There is a bit different of culture between Far East Asian and Western. What is acceptable in Far East Asia might not be acceptable for Western and vice versa. My experiment with the Western People: No need to talk to much, just show on your works that you deserve to be respected.
i noticed similar things. western culture is more result driven, where as asian culture (generalization i guess) based a lot more on the relationships.
Here's a report from WSJ: http://blogs.wsj.com/indiarealtime/2012/08/04/nehwal-wins-bronze-after-wang-xin-suffers-injury/ "At one point Nehwal was down 15-9, after which she made a comeback worthy of praise. It was a close game but Wang eventually won the first game 21-18. Just before the end of the first game, Wang suffered an ankle and knee injury. By the time the second game started, it became clear she was unable to continue and bowed out. Nehwal was declared winner." Reviewing over the full video, with the exception of the first 5 points when Wang made a few unforced errors, she'd been commanding the game, keeping a min. of 5-6 points lead. When the score got to 20-14, she appeared to have slipped (slightly) on her left around mid-court area. Since then, she showed some sign of troubles.
