These charming girls are the students of the College of Civil Aviation in Chengdu, Sichuan Province. Trainee stewardesses practice a graceful smile by holding a chopstick between their teeth. They also place magazines on their heads to achieve the perfect posture.
Another exercise that helps the girls to get great posture is balancing. Student air hostesses have to balance a glass bottle on their heads for three minutes.
Trainee stewardesses also hold a piece of paper between their knees in order to learn how to stand properly.
Young men and women undergo rigorous posture training to ensure they behave appropriately during the flight.
Safety is also a big priority at the College. There are even special classes where students are taught survival skills and martial art techniques like Kung Fu and Taekwondo.
