More than 20 students from Sichuan Southwest Vocational College of Civil Aviation staged a fashion show in traditional Han costumes and train attendant uniforms Saturday onboard a train along the newly opened high-speed railway linking Xi'an and Chengdu. 

The students, majoring as train attendants, were volunteers for the train carriage, themed on the style of the Qin and Han dynasties.
