a fun fact that actually both has same surname Lin Dan: 林丹 (http://en.wikipedia.org/wiki/Lin_Dan) Liem Swie King: 林水镜 (http://en.wikipedia.org/wiki/Liem_Swie_King) both are excellent player in badminton in their era both are MS player (Liem Swie King also play MD) why Liem? because Liem is Hokkien way to say Lin http://en.wikipedia.org/wiki/Lin_(surname)
Lin 林 is one of the most popular Chinese family name. But interesting there aren't many famous badminton players with this family name. But instead there are many famous movies stars and singers with this family name. Maybe Wang is better for badminton and Lin is better for performing artists.
In light of his recent spate of brilliant acting performances, I would say you were right about Lin Dan. (sorry, couldn't resist that one )
Lin (林)is the 17th most popular lastname/surname/familyname is China. while Wang (王) is the 2nd, and we wonder why we have so many Wangs. Li/Lee is the 1st. we have a few Li's among the badminton pros. Zhang (张) is the 3rd most popular and we have our share of those as well.
李王张刘(Li/Lee, Wang, Zhang/Cheung, Liu/Lau) are the four major family name in China (or for Chinese, whichever country/region). Hence, not surprise seeing 李王张 in the first three position. But pondering why 刘 is missing.
