China completed an unprecedented clean sweep of gold medals to end their controversial London 2012 tournament with an emphatic statement. Defending champion Lin Dan led the way with a victory over arch-rival Lee Chong Wei that surely erases any doubt over whether he is the greatest player of all time.
Li Xuerui left no doubt who was the best women's player in the world when she beat the world champion, Wang Yihan.
Cai Yun and Fu Haifeng then wrapped up the job for China by seeing off Denmark's Mathias Boe and Carsten Mogensen in their final.
Lin beat the Malaysian Wei 15-21, 21-10, 21-19.
