The newly paired-up Ma and Guo were beaten 11-7, 11-13, 11-9, 9-11 and 12-10 by Lee Jong Woo and Lee Eun Hee in the morning after Ma sent a receive into the net.

"At the end of the match, I moved back too far away from the table and granted the opponents a 11-10 lead, and for the match point, we just lost the control," commented the 18-year-old Ma, who is making his debut in the Asiad and paired up with Guo Yan for the first time.

"Also we were too much intimated by the tense of the game," he added.

Guo Yan echoed: "We missed several good chances and we need more time to improve our teamwork."

The Korean pair of Lees will next face Singapore's Yang Zi and Li Jia Wei, who knocked out Hong Kong pair Li Ching and Tie Yana, 2-11, 4-11, 11-8, 11-8, 11-2.

"We have met each other a lot of times and I know exactly how she plays," said Wang.

Wang took the game 11-7, 11-7, 11-6, 12-10 with patient play and she will next play Tie Yana of Hong Kong, who overcame Japan'stop paddler Ai Fukuhara 5-11, 11-9, 13-15, 11-8, 11-8, 7-11, 11-8.

"Right now, I just start to feel a bit tired," said the 28-year-old.

China's teenage paddler Guo Yue also reached the singles semifinals with a 4-0 win over Kim Mi Yong of DPR Korea and will face Olympic semifinalist Li Jia Wei, who beat South Korean Kwak Bang Bang 3-0 in a clash of two former Chinese.
