Noted for her consistency, anticipation, forecourt prowess, and sporting smile, Gao is one of the most successful doubles players in the history of women's badminton.

She and Zhang Jun won consecutive gold medals in mixed doubles at the 2000 and 2004 Olympics, overcoming severe tests in both.

Their All-England streak was finally broken in the semifinals of the 2007 tournament by fellow countrywomen Zhang Yawen and Wei Yili.

Gao has shared five All-England mixed doubles titles: three with Zhang Jun (2001, 2003, and 2006), and two with Zheng Bo (2007 and 2008).

She has been a member of the perennial world champion Chinese Uber Cup (women's international) team since 2000.
