As the most successful women's program in badminton at the Olympics, Chinese female shuttlers have racked up 10 gold medals — both singes and doubles combined — at the Games since the sport's debut in 1992.

Now, with Chen still at her best and the country's second-ranked singles ace He Bingjiao tested and improved at the Uber Cup, the Chinese women's contingent, which also boasts world No 1 doubles pair Chen Qingchen and Jia Yifan, looks primed for Paris.

Chen Yufei got the host's final against Indonesia off to a flying start, conquering 9th-ranked Gregoria Mariska Tunjung, 21-7, 21-16, to complete the opening singles rubber in just 38 minutes.
