Chen will next face Jan O Jorgensen of Denmark, who saw off another Chinese shuttler Huang Yuxiang 24-22, 21-17.

In the women's singles, China's trio of Chen Yufei, Gao Fangjie and Chen Xiaoxin all made a step forward.

Fourth-seeded Chen Yufei bounced back from one game down to shrug off Nitchaon Jindapol of Thailand 20-22, 21-14, 21-8.

Gao Fangjie overcame Japanese Aya Ohori 23-21, 21-18, and Chen Xiaoxin stood firm to beat Russia's Evgeniya Kosetskaya 21-16, 16-21, 21-13.

The three joined He Bingjiao and Cai Yanyan, who had gone through on Tuesday, in the second round.

Other prominent names, including world No. 1 Tai Tzu Ying of Chinese Taipei, also secured their places in last 16.

Chinese pairs continued their strong performance in men's doubles after triumphing both duels against Danish rivals, meaning that all four pairs stayed in contention.

Liu Cheng and Zhang Nan, the tournament's third seeds, outclassed Mathias Boe and Carsten Mogensen 21-11, 21-15. He Jiting/Tan Qiang rallied past fifth-seeded Kim Astrup/Anders Skaarup Rasmussen, the China Open champions last month, 22-24, 21-18, 21-17 in 70 minutes.

It was totally different scenario for their women's counterparts. China's Huang Dongping and Huang Yaqiong unsurprisingly lost to top-ranked Yuki Fukushima/Sayaka Hirota of Japan 21-11, 21-12.

Du Yue and Li Yinhui withdrew due to Du's foot injury, handing their Indonesian opponents Greysia Polii and Apriyani Rahayu a walkover.
