China beat Indonesia to reach Sudirman Cup semis

"Neither of us felt very nervous, but maybe because of that, we didn't notice that our bodies were too relaxed to play," Huang commented on the thriller.

"We haven't played the mixed team competition for a long time, so I was a little overwhelmed when I came on court," said Zheng.

"When we were 19-14 down in the second set, I suddenly felt like there were clear chants and cheers behind us. Then we believed we had something to lean on."
