LI NA admitted she was stunned after upsetting Russian fifth seed Svetlana Kuznetsova to become the first Chinese player to reach the last 16 at Wimbledon.
Li Na, the 27th seed, will now face Nicole Vaidisova of the Czech Republic tomorrow for a place in the quarter-finals.
"When I was in the locker room afterwards I couldn’t believe it," said the 24-year-old from Wuhan.
Li Na believes her decision to return to college in 2003 before resuming her tennis career has been one of the major reasons for her success.
"Definitely that helped, before I was just a little girl and when something happened on court I couldn’t really think properly," she added.
"I think now I’ve grown up."
Zheng Jie, China’s world No 37, said she was delighted by Li Na’s achievement.
Zheng Jie, who was beaten in straight sets by Belgian second seed Kim Clijsters in the third round, said she was not surprised by Li Na’s 2-6, 6-2, 6-3 victory over Kuznetsova.
"I was not surprised that she beat her this time," said the 23-year-old.
"Two years ago she played her in the China Open and had two match points but she lost.
"She said yesterday morning that when she plays Kuznetsova she always loses in three sets but I told her she could win next time!"
Zheng Jie said she was pleased with her own performance in reaching the third round at only her second Wimbledon and was full of praise for Clijsters.
"She has a lot of power and a big serve," said Zheng Jie. "I returned well today but her serve is so strong that I didn’t have the chance.
"I think it isn’t bad to get to the third round as in China there are no grass courts."
Clijsters paid tribute to the Chinese girl.
"She’s a tough player. I played against her once in Hong Kong in an exhibition. It was a close match," said the Belgian. "She’s a counter-puncher. She likes to play fast rallies and likes to stand on the baseline and dictate the points.
"It was important for me to keep moving her side to side and not let her play her game."
Li Na, who clinched her first tour title at Guangzhou in 2004, is making her debut at Wimbledon and is the first Chinese player to be seeded at a Grand Slam.
