The catwalk is no cakewalk

Dan Jiani, a top car show model, says achieving success in the profession requires a lot of hard work. He Na reports.

It's - 2 C outside in a suburb of Beijing, and Dang Jiani is leaning against a black luxury car with a smile on her face.

She's wearing a short silk red dress, with her arms and legs exposed to the cold. Dang is here for a photo shoot to promote a new car. When the photographer stops to take a break, Dang quickly puts on warmer clothes and jumps to keep her legs and feet from freezing.
