Halloween (or Hallowe’en) is an annual holiday observed on October 31, primarily in Ireland, Scotland, Canada and the United States. It has roots in the Celtic festival of Samhain and the Christian holiday All Saints’ Day, but is today largely a secular celebration. Says Wikipedia, but Halloween is no longer confined to the above mentioned Anglo Saxon countries. Halloween has spread it’s bat wings across the globe like Valentine’s Day has. From the United States of Trick or Treat to China, scary masks and funky costumes are the norm on Halloween.

An artist prepares to perform at the Shanghai Nightmare haunted house attraction in Shanghai October 27, 2010. China's first Halloween haunted house attraction, which opened in 2009, is spooking the crowds in Shanghai, with its creators hoping to cash in on the traditions of the ancient, but essentially Western, festival to commemorate the dead. While China has a rich tradition of ghosts and ghouls of its own, Halloween is a non-event for most Chinese, who hold their own commemoration for the dead during the Qingming festival or Tomb-Sweeping Day, usually marked in April. The creators of the haunted house, American-Chinese Gan Quan and wife Xu Jiali, said it's about time Chinese got a taste of Halloween.
