All Grand Slams congratulate Chinese gold

The social media accounts of all four Grand Slam tennis tournaments - the Australian Open, French Open, Wimbledon and US Open - posted congratulations to Zheng Qinwen, who became the first Asian player to win the women's singles gold at the Olympics.

At Roland Garros, Zheng defeated Donna Vekic of Croatia 6-2, 6-3 to seize the women's singles gold, which is China's second Olympic tennis gold, following Li Ting and Sun Tiantian's crown in the women's doubles at Athens 2004.
