The Chinese duo needed only one hour and 30 minutes to thrash the Chinese Taipei pair 6-1, 7-6 (5) to bring the second gold medal for China in the Asiad tennis tournament.

Zheng Jie also won the women's singles title on Wednesday, beating India's Sania Mirza in the final.

"In the second set, our opponents played very well. They were a real threat to us. This is a final match so we were a little bit nervous, but we were able to keep up," said Yan Zi, who is ranked fourth in the world in the women's doubles.

"Whenever an opportunity came, we tried to seize it, but sometimes we played impatiently. We just tried to keep the score tight and never really thought about the gold medal," she added.

Australian Open and Wimbledon winners Zheng and Yan had three breaks in a row to take the first set 6-1 and then combated off a 0-3 deficit in the second and held on to force a tie break, where the Chinese finished with 7-5.

"We trained very hard so we were well-prepared. We are very happy to win the gold medal as it is my first Asian Games gold medal. We will try to keep the form and achieve the good results next year," said Yan.
