At the Chen Jing Lun Sports school in the picturesque city of Hangzhou, the slogan "Today's sports school student, tomorrow's Olympics stars" greeted all those who entered, and it was prescient greeting that proved true for one little girl, Olympics swimming sensation Ye Shiwen. At 16, Ye's powerful strokes and rapid laps won her gold in the 200 meters individual medley and the 400 medley in London this week; But as she shattered world records and smiled for the cameras, her swift timings led some to speculate, without proof, that she might be taking performance-enhancing drugs. But at the pool where Ye got her first dip at 6 years old, Ye's childhood coach Wei Wei said her success is boiled down to good genes and prodigious hard work. [Photo/Agencies]
