Yong-dae Fabulous He Lee Yong-dae
As usual, 21-year-old Lee Yong-dae has a good stamina and wonderful performance that he is able to reach two semi-finals. In the men's doubles, Yong-dae and Jung Jae-sung (27) overpowered home players, Guo Zhendong/Xu Chen 21-14 and 21- to compete against fourth seeds, Mathias Boe/Carsten Mogensen.
However, Yong-dae/Jae-sung's success is not followed by countrymen Shin Baek-cheol/Cho Gun-woo. Baek-cheol and Gun-woo, both of whom had been Yong-dae's partners, bowed down to Koo Kien Keat/Tan Boon Heong after giving a tough fight. Kien Keat and Boon Heong struggled hard before winning the match 15-21, 21-18, 21-18.
Singles' Semi-final-Ticket Bookers
In the men's singles another Korean player, Park Sung-hwan, has the opportunity to meet one of the world's best badminton players, Lin Dan. Sixth-seeded Park needed to pay the semi-final ticket with a marathon match against China's Du Pengyu, 23-21, 18-21, and 21-14, in an hour and 15 minutes.
Meanwhile, world champion Lin Dan just needed 37 minute to humble Indonesian Simon Santoso in a comfortable 21-12, 21-12 win. In the top half, Lin Dan's teammate Chen Jin defeated Simon's teammate, Sony Dwi Kuncoro, 21-16, 15-21, and 21-12, to take on Danish Jan O Jorgensen.
O Jorgensen, who shocked top seed Lee Chong Wei by giving Lee a first round exit, continued his success to the last four after prevailing over Thailand's number one Boonsak Ponsana 21-11, 21-19.
In the women's singles, Wong Mew Choo failed to prevent all-Chinese semi-final by surrendering to China's Wang Shixian 10-21, 22-24. Mew Choo, the China Open 2007 winner, led 11-7 in the second set and left Wang 20-19 and 22-21. Nonetheless, she could not maintain her position and let Wang equalized the score 22 all and then won 24-22.
Wang will play the only seeded player, Jiang Yanjiao, in the semi-final. In the bottom half, qualifier Li Xuerui stunned world champion Lu Lan in only two sets, 21-17, 21-19, to face Wang Xin in the semi-final.
