Zheng Jie, one of China's most successful female tennis players, married relatively unknown former tennis player Zhang Yu in 2006. Zhang represented China at the Davis Cup five times in the 1990s but never got past the preliminaries. He retired from competitive tennis in 2000. Their relationship may be unusual, but it works for this young couple. Zhang said, "The strong will and power in her inner heart attracted me a lot. Despite the discrepancy in our careers, I am ok with my role.""All Chinese girls should marry a man like Zhang," Zheng once said, "He supports me unselfishly. He is not only a husband, he's also a great friend and a great coach as well. I want to say 'thank you so much' to him. I had some very hard times during my career. I would not have been able to win without him."
