Team China's double delight

Luo Yigang, singles coach for Team China, hailed the Chengdu run as a critical tuneup for his athletes, especially in the high-stakes team format, in time for the ultimate test in Paris.

"We didn't get to play some of our toughest rivals this time, but no one should take the credit away from our players," Luo said in the post-final news conference on Sunday.

"They overcame strong challenges from within, dealing with the pressure, making a stand for the whole team.

"The experience here is invaluable and will help us go for golds at the Paris Olympics," said Luo.

"We did a good job as a team, I am extremely happy," said reigning Olympic singles champion Chen Yufei, who is ranked second in the world after South Korea's An.
