"We ran out of gas at the final point and it was a huge relief knowing that we kept the team's lead collectively by completing our part," said Chen Qingchen.

"We prevailed counting on our never-give-up spirit no matter how far we fell behind in the scores. The fight we had when we were playing on the verge (of a loss) carried us through. It was a great test for the next match," said Jia.

Team China, as the most successful program in the biannual championship's history with 15 titles, will compete for its 16th Uber Cup trophy on Sunday against Indonesia, who stunned defending champion South Korea 3-2 in another semi clash on Saturday.
