The origins of Halloween go back to ancient Celtic traditions in Ireland. According to Celtic mythology， November 1 marked the end of summer， and it was then that the boundaries between the natural and the supernatural were believed to disappear， and spirits of the dead moved freely among the human world. It is interesting to see certain parallels with the Chinese Ghost Festival， also known as the Hungry Ghost Festival in southern China and Southeast Asia. It falls on July 15 of the lunar calendar， or mid-August of the Gregorian calendar. On that day， Chinese legend says， the gate to hell is opened at midnight， and ghosts swarm into the world of human beings in search of food and money. These ghosts， who have been starving for a whole year， will enter households if they cannot find enough delicacies in the street. Therefore， people in southern China traditionally put chicken， meat， vegetables， rice， tea and fruit on their doorsteps that day. In Chongqing， the streets that night are empty， as few dare to leave their house. The legend says that if a ghost finds you in the street and follows you back home， your family will have bad luck all year. All in all， people should be very careful during the Chinese ghost festival; they have to keep away from ghosts and not offend them. It’s really not as much fun as Halloween.
