Zhang has a more achievement with Zhao in the mixed doubles event rather than with Chai. Zhang and Zhao won 2010 Yonex Japan Open Super Series title after compatriot Tao Jiaming and Tian Qing 21–19 and 22–20. Meanwhile, Zhang and Chai's journey in Tokyo was ended by seniors Cai Yun and Fu Haifeng in the semi-finals, losing 17–21 and 16–21.
In China Open Super Series, Zhang attended the men's and mixed doubles finals but he lost in both events. In the men's doubles, South Korea's Lee Yong-dae and Jung Jae-sung emerged as the winners as they downed Zhang and Chai in straight sets, 21–15 and 21–12. In the mixed doubles final, Tao Jiaming and Tian Qing took revenge with a 21–18, 21–17 triumph over Zhang and Zhao.
Zhang only played in mixed doubles in the last super series tournament of 2010, Yonex Sunrise Hong Kong Super Series. seeded 5, he and Zhao reached the final but lost in a long three-set match against Joachim Fischer Nielsen and Christinna Pedersen of Denmark 20–22, 14–21, and 22–20.
Zhang and Chai also played in the VICTOR-BWF Super Series Finals 2010, yet both are conquered by Lee Yong-dae and Jung Jae-sung in the last four 15–21 and 11–21 in just 30 minutes.
Once again, Zhang and Zhao met Tao Jiaming and Tian Qing, now in Korea Open Super Series Premier final. Zhang and Zhao vanquished their teammates 21–17, 13–21, and 21–19 to become the first winners of Super Series Premier.
