Paris (CNN) -- There's more to being a model than just looking pretty, according to Liu Wen. And she should know. Liu is one of the world's highest-paid models and the first Chinese face to crack the top five in Forbes' annual list of top earners. She says that far from being a week long party, Paris Fashion Week is an arduous mix of shoots, shows and limited sleep. Models, even well-known ones like Liu, turn up at fashion week with no shows booked and are often slotted in just 24 hours before the shows are scheduled to start.
