Chinese young women holding plates walk as they receive etiquette training at a vocational school for the upcoming Beijing 2008 Olympic Games medal ceremonies' hostesses in Beijing, China, Wednesday, Jan. 9, 2008. The polished young women practice proper posture by balancing books on their heads while squeezing a sheet of paper between the knees. A perfect smile is one that reveals six to eight white teeth, a skill honed by hours in front of a mirror while carefully clasping a chopstick between the canines.
