Elizabeth Cann leads the British charge in the women's singles of the World Championships as the only player to make the second round.
Cann's 16-21, 21-13, 21-11 victory against Michelle Chan Ky sets up a second-round tie against Thailand's 10th seed Porntip Buranapraser.
The Commonwealth Games bronze medallist commented: "It's going to be tough from now on.
"I've got nothing to lose if I can build on how I've just played."
Cann, 32, fought back after losing the first set to comprehensively win the next two sets and take the match in 46 minutes.
Scotland's Susan Egelstaff lost 22-20, 21-16 to Michelle Li of Canada, while England's Sarah Walker lost to Pi Hongyan in the opening round.
Egelstaff, six-time Scottish champion, said: "I'm disappointed to lose but it was a pretty tight game. She (Li) just played better on the important points. I don't think I played badly."
Wildcard entry Walker was beaten by Pi Hongyan (21-12, 21-8).
