A picture made with a tilt-shift lens shows “Dwarf Empire” cast member 19-year-old Han Zhen Yan posing in her fairy costume backstage outside one of the fairy tale-like houses at the Dwarf Empire theme park outside Kunming, China's Yunnan province, 04 April 2013. The Dwarf Empire theme park opened in mid-2009, employing a number of dwarves to create the show. Depending on what type of job they do at the park, employees earn between 800-2,000 CNY (100-250 Euros) per month, most of which goes towards their savings as lodging is provided, and their living quarters are equipped with kitchens where they prepare their own meals.
