The newly released Chinese movie "Legend of the Demon Cat" used authentic architecture to recreate the glory of the Tang Dynasty. Director Chen Kaige built the film set in Xiangyang City, central China's Hubei Province, but it was modeled after the Tang-dynasty capital Chang'an in one-to-one scale. Some buildings on set are very special and mimic the curved city walls. Art designer Tu Nan said they tried to differentiate the structures on set using colors, to deliver a better visuals. He added that the marketplace is also full of special designs and historically accurate materials.
