Hong Kong badminton stars Tse Ying-suet, Jordan Tang and Lee Cheuk-yiu were among SAR players securing wins in their first games at the Hong Kong Open on Wednesday.

Mixed doubles pair Tse and Tang won 22-20, 21-17 against Chinese Taipei's Hsu Yin-hui and Paris Olympics gold medalist Wang Chi-lin, who's competing in both the mixed doubles and men's doubles events at the Hong Kong Coliseum.

Team Hong Kong, China's top men's singles player, Lee Cheuk-yiu, beat the national team's Lu Guangzu 21-19, 21-18.

Joining Lee in the round of 16 is the SAR's 20-year-old Jason Gunawan, who stunned last year's runner-up at the tournament, Kenta Nishimoto from Japan, 21-13, 21-18, to the delight of a roaring home crowd.

Hong Kong's Angus Ng, however, was swept aside by the tournament's top ranked player, Dane Viktor Axelsen, 11-21, 12-21.

In the women's singles, Paris Olympian Happy Lo was knocked out by fellow SAR shuttler Saloni Mehta 14-21, 21-9, 17-21.

Former world number one Tai Tzu-ying from Chinese Taipei, who's playing in her last Hong Kong Open before retirement, is also through to the last 16.
