Trainee flight attendants dressed in Cheongsam (qipao) attend an event promoting responsible tourist behavior in Chengdu, capital of Southwest China’s Sichuan province. The would-be attendants from Chengdu East Star Airlines and Travel College based themselves at scenic spots in the city to remind tourists not to pollute the environment by littering, for example, or act in an unruly manner during the May Day holiday from May 1 to 3.
