More than 20 future flight attendants stage a flash mob show in Chengdu, capital of southwest China's Sichuan province, May 3, 2015. They displayed traditional Chinese clothing and calligraphy, aiming to celebrate China's Youth day that falls on May 4 every year.

The models, mostly post-1995s, are all college students from Sichuan Southwest Vocational College of Civil Aviation. The clothes were designed and made by a model community named "Yanruyu" (literally ladies as fair as jade). Most of the models have already been selected as flight attendants by many airlines in China.
