Feng, who was defeated in the first round of last year's tournament, upset London 2012 silver medallist Ding to win 11-8, 5-11, 5-11, 12-10, 11-9, 8-11, 11-3.

The 26-year-old, who gained Singaporean citizenship in 2008 after moving from her native China in 2007 under the Singapore Foreign Sports Talent Scheme, fell at the final hurdle despite her impressive performance, losing out to Liu Shiwen of China by four sets to two in the final.

In the men's singles, China's reigning Olympic and world champion Zhang Jike came from a set down to defeat his compatriot Ma Long 6-11, 11-8, 11-6, 11-8, 11-4 in the final.

The singles finalists teamed up for the men's doubles final, but it was disappointment for Zhang and again for Long as they were defeated by fellow Chinese pair Xu Xin and Yan An by three sets to one.

In the women's doubles, it was victory again for China as Ding and her partner Li Xiaoxia ruthlessly crushed Japanese pair Kasumi Ishikawa and Misaki Morizono, 11-4, 11-5, 11-9 in the final.
