Ma Jin
Ma Jin (; born 7 May 1988) is a badminton player from China who specialises in women's and mixed doubles. She partnered Wang Xiaoli in women's doubles and excelled in the category until 2010 when both players are split after China failed to defend their Uber Cup against South Korea in Kuala Lumpur. Consequently, Ma Jin was unable to continue competing in the women's doubles event without her regular partner and she had to concentrate on mixed doubles instead. Ma Jin had tasted successes in mixed with several partners, notably Zheng Bo, He Hanbin and Xu Chen. Her domination at the front of the court combined with the power play from Xu Chen made them one of the most dominant Chinese pairs to date, the other being Zhang Nan and Zhao Yunlei.
