The Chinese duo lost in the final of the Tokyo Games three years ago but set the record straight with a 21-8, 21-11 victory over Kim Won-ho and Jeong Na-eun.

Backed by huge support from Chinese fans inside La Chapelle Arena, Zheng and Huang stormed into an early lead and took the first game in less than 20 minutes.

The South Korean pair made a better start to the second game but Zheng and Huang were relentless, eventually closing out the match when Jeong hit a return wide.

Japan’s Yuta Watanabe and Arisa Higashino took bronze after a 21-13, 22-20 win over South Korea’s Seo Seung-jae and Chae Yu-jung.
