World No. 13 Sindhu, who lost thrice to Ying in the past, recorded a dominating 21-12 21-15 win over the third seed in a women's singles match that lasted 34 minutes at the Odense Sports Park here.
The Hyderabadi will next take on sixth seed Chinese Wang Yihan, who is also a 2011 World Champion and silver medallist at 2012 London Olympics and a former World No. 1.
Sindhu produced a dominating game as she lead 4-2 early on and then kept extending the lead to eventually seal the opening game.
In the second game, Ying tried to put up a fight and opened up a slender 4-2 lead but the Indian clawed back in no time and broke off at 8-8 to move to 14-9 lead. Ying narrowed down the lead to 13-14 but she could never wrest control as Sindhu marched on to shut the door on her higher-ranked opponent.
