This simple training room at Qin Huang Dao Sports School is where Cao Lei's Olympic dream started.

15 years ago, the 10-year-old girl began her successful sports career.

Li Ting, weightlifting coach of Shanhaiguan Sports Bureau, said "This barbell was once used by Cao Lei. It has been used in training for 20 years. With such simple equipment, we cultivated a world champion. Cao Lei made tremendous efforts during the process."

The young girl's painstaking work has left an impression on everyone at the school. She was always the last to leave the training room.

When talking about her development, many people agree her father, Cao Guochen, played a pivotal role in her success.

In his younger years, he was a weightlifter in his hometown. He says he has been very strict with his daughter, and has pushed her very hard, because he knew one day she would be a champion.

Cao Lei's father Cao Guochen said, " At that time, I sat behind her watching her practicing. My daughter shouldered the barbell, with tears on her face."

Two years ago, Cao Lei followed her coach's advise and shifted from the 69kilo to 75kilo weightlifting division. After a period of adapting and training, she made great strides in many competitions.

Some of her teammates say Cao Lei is always at her best in the big competitions. With her golden results at her first Olympic Games, there is no doubt she will lift more success in the future.
