A new martial arts blockbuster is bringing fresh attention to northwest China. After serving as a key filming location for the film "Blades of the Guardians," the city of Karamay in Xinjiang has launched a series of tourism incentives, offering discounts and vouchers to visitors. The campaign is drawing movie fans to explore the city's dramatic desert landscapes, including the striking Yadan landforms of World Ghost Town, where much of the film was shot.
