Cheng Fei is China's top prospect for gold in woman's gymnastics. The 20-year-old, who will go head-to-head with U.S. hopeful Shawn Johnson, left home at age 7 to take part in China's grueling state-sponsored program to groom elite athletes. Her greatest strengths are the floor exercises and vaulting. If she wins, team sponsor Samsung will no doubt have plenty of plans for her.
