World No. 1 Lin Shidong of China edged An Jae-hyun of South Korea 3-2 in the men's singles round of 16 at the World Table Tennis (WTT) Champions in southwest China's Chongqing Municipality on Thursday.

That brought up a decider in which Lin built his advantage point by point with a steady performance, before sealing the deal 11-5. His opponent in the quarterfinals will be Lin Yun-ju of Chinese Taipei.

On the women's side, top-seeded home paddler Sun Yingsha beat Doo Hoi Kem of China's Hong Kong Special Administrative Region (SAR) 11-5, 11-3, 11-6 to book her place in the last eight.
