NANJING, China, July 31 (Xinhua) -- China's He Bingjiao clinched a spot in the round of 16 at the 2018 BWF World Championships women's singles event, after beating Yip Pui Yin of Hong Kong in two straight games 21-11, 21-17 here on Tuesday.

The 2014 Youth Olympic champion faced a strong fightback in the second game after an easy win in the first, and the two players traded the lead until 18-17, when He won three consecutive points to wrap up the victory.

"I played downwind in the second game and had to focus more on the control of the shuttle, so I made more mistakes," the 21-year-old said.

He Bingjiao came into the match having received a bye in the first round. She will take on Thuy Linh Nguyen of Vietnam in the last 16, who upset Canada's 13th seed Michelle Li in the second round.

"Last year I finished in the round of 16 in Glasgow, and this time I want to go further," He said.

Elsewhere, Fourth seed Ratchanok Intanon of Thailand survived a tough three-game battle against Mia Blichfeldt of Denmark to secure a place in the last 16. Intanon found herself in a tough spot in the second game, trailing by 19-16 after having lost the first 21-16, but the Thai found her form just in time to win four points in a row to win 22-20. With her confidence having returned, the 2013 champion then sealed the victory with an easy 21-10 win in the decisive third game.

Intanon now takes on tenth seed Saina Nehwal of India, who defeated Turkey's Aliye Demirbag 21-17, 21-8.
