Top seed and local favourite Chou Tien Chen made it safely through to the third round of the Chinese Taipei Open on Wednesday.
The World No 5 came through a tight opening game against Zin Rei Ryan Ng before taking control of the contest in the second for a 22-20, 21-11 victory.
The 27-year-old moves on to face countryman Chu Han Chou, after he advanced when his second-round opponent, Vladimir Malkov, retired during their match.
Chu was leading 22-20, 16-17 when his 12th-seeded opponent was forced to call it a day.
Others to advance on the day included two more local hopes – second and third seeds Tzu Wei Wang and Hsu Jen Hao – as well as seventh seed Wei Feng Chong.
The only major upset of the day saw fifth seed Iskandar Zulkarnain of Malaysia go down 21-15, 18-21, 21-19 to countryman Giap Chin Goh.
The women’s draw also got under way with first-round action, with several top seeds suffering early exits.
Fourth seed Chiang Mei Hui, sixth seed Ying Ying Lee and seventh seed Su Yu Chen were all eliminated.
Second seed and home favourite Hsu Ya Ching and third seed Jin Wei Goh of Malaysia both made it safely through to the second round, however.
