Chinese pairs all made it through to the quarterfinals in men's doubles, women's doubles and mixed doubles, while Wang Hao and Ma Long came out the only duo who struggled, before winning over their Chinese Taipei opponents.

Wang and Ma, who had never paired up before coming to Doha for the Asiad, were pulled into full sets before rallying to earn a berth in the men's doubles quarterfinals.

"We've not tuned up with each other, and it's hard for us to face the true challengers here for the first time," said Wang Hao,who earlier partnered with Ma in the morning session to beat the hosts Qatar's Ahmed Ahmed and Mohammed Al Saadi 3-0.

In a match of Round of 16, Wang and Ma opened with one set dow but they managed to hold their nerves to edge out Chang Yen Shu and Wu Chih Chi of Chinese Taipei 9-11, 11-5, 11-7, 10-12,11-7.

"The close-door training camp helped us a lot play as a pair, but it felt quite different to play on court," said Wang, who was crowned the men's doubles champion with Kong Linghui last year at the Shanghai world championships.

Teenage paddler Ma Long took a overstrung match to blame as he and his partner committed too many unforced errors.

"I could not hold my nerve in the beginning, and wasted a lot chances in some key shots" he said.

"We should have made it easily if we were more confident," sai the 18-year-old Ma.

The pair will face Japanese Seiya Kishikawa and Jun Mizutani, who overcame Singapore's Gao Ning and Yang Zi 8-11, 12-10, 11-9, 11-6.

In the other Chinese match, Olympic gold medal winning duo ChenQi and Ma Lin took just seven minutes to knock out Mohammed Al Hashedi and Wael Al Qershi from Yemen, 11-5, 11-5, 11-3, setting up a quarterfinal clash against Cheung Yuk and Leung Chu Yan from Hong Kong, China.

On the women's part, Chen Qing/Wang Nan and Guo Yue/Li Xiaoxia appointed meetings respectively with Singapore's Li Jia Wei/Sun Bei Bei and South Korea's Kim Kyung Ah/Park Mi Young.

Mixed doubles pairs of China, Ma Lin/Wang Nan and Ma Long/Guo Yan both enjoyed 3-0 wins, against DPR Korea's Kim Song Chol/Ryom Won Ok and Ri Chol Guk/Kim Mi Yong, while in the men's and women's singles, Ma Lin, Wang Hao, Wang Nan and Guo Yue made it through easily.
