China's Zheng Jie continued to surprise all the tennis fans back home. She became the first Chinese player to reach the semifinals of a Grand Slam tournament Tuesday, beating Nicole Vaidisova 6-2, 5-7, 6-1 at Wimbledon.

The 24-year-old has also become the first female wild-card entrant to ever reach the semifinals at the All England Club and second at any Grand Slam.

Zheng Jie expressed her excitement after the game.

"My thinking is much simpler. I've never thought I can make it to the semifinal."

In only her third appearance at Wimbledon, the 133rd-ranked Zheng Jie has so far beaten French Open champion Ana Ivanovic and three other seeded players.

On Thursday, she will face eight-time Grand Slam champion Serena Williams, who has won the title at Wimbledon twice in her career.

Zheng Jie and Williams have only met once before, with the American winning in straight sets in the first round at Wimbledon in 2004.

At the same time, Elena Dementieva and Venus Williams, who have both won in the quarterfinals, will compete for another ticket to the women's final.
