On the 15th day of the 7th lunar month each year, the gates of the Underworld open, allowing ghosts and spirits to walk the Earth. Instead of calling for the exorcist, today the Chinese celebrate the dead, putting on elaborate performances and making offerings to the wandering souls. Though rooted in Buddhism and Taoism, China's Ghost Festival began as a harvest holiday that marked the changing of the seasons and is now a festival celebrating folk traditions. The celebration shares striking similarities with many others around the world, such as Halloween and Mexico's Day of the Dead. Where better to hold the festivities than in southwest China's "Fengdu Ghost City," the capital of the Underworld according to the Chinese classic "Journey to the West"?
