Johanna Konta put the disappointment of defeat in the China Open final behind her to kick off her Hong Kong Open campaign with a 6-2 6-2 win against compatriot Naomi Broady.
Two breaks in each set proved enough for Konta - a new addition to world's top 10 - to brush aside Broady, facing a single break point as she dominated on her own serve.
Another British player, Heather Watson, joins Konta in the second round following her 7-5 7-6 (11-9) win against Marina Erakovic and will now take on fifth seed Caroline Wozniacki, who knocked out Zheng Saisai 6-1 6-4.
Sam Stosur was the biggest casualty of the day, with the Australian fourth seed losing 6-3 6-4 to Japan's Nao Hibino.
Top seed Angelique Kerber made an assured start to her challenge by seeing off Maria Sakkari in straight sets, while defending champion Jelena Jankovic hammered Samantha Crawford 6-3 6-1.
Elsewhere, there were wins for Wang Qiang, Bethanie Mattek-Sands, Kristina Mladenovic and Caroline Garcia against Zhang Ling, Basak Eraydin, Dalila Jakupovic and Tereza Martincova respectively.
