BEIJING, Aug. 15 (Xinhua) -- No. 2 seeds Du Jing and Yu Yang defended the glory of Chinese women's double shuttlers who secured the gold in previous three Olympics by defeating Lee Kyung-won and Lee Hyo-jung from South Korea 21-15, 21-13 here Friday.

　　The up-and-coming pair of China, who beat their compatriots Wei Yili and Zhang Jiewen in the semi-final, shouldered the huge responsibility after defending champions Yang Wei and Zhang Jiewen lost to a Japanese pair in a quarter-final.

　　Du and Yu didn't let down the enthusiastic spectators in the Beijing University of Technology Gymnasium, and consistently exhibited their powerful attacks in the first game, which was interrupted by a requirement of emergent medical care from Lee Kyung-won, apparently injured in her left ankle.

　　In the second game, the Koreans led the score till 11-11, after which the Chinese pair staged a 10-2 run and sealed the game at 21-13.
