World champion An experienced a straight-set loss to China's Wang Zhiyi 21-12, 21-16, saying that she hasn't fully recovered from injury. "I hope to return to the court as soon as possible, so I am here. But unfortunately, I can't play very well now."

"I think the injury did influence her performance. It was not the best An. But still, she is a very tough player and I need to learn from her," commented Wang.

China's Chen Yufei, seeded third, also advanced to the quarterfinals after defeating Goh Jin Wei of Malaysia 21-9, 21-16, reports Xinhua.

"It was a tough game. I tried my best, so I finally won. I am really happy now. But I know it's not the end. I still need to focus on the upcoming match," said Popov.

The men's doubles competition saw the top two seeds advance to the last eight, as India's Satwiksairaj Rankireddy and Chirag Shetty, alongside China's Liang Weikeng and Wang Chang, overcame their opponents respectively.
