Halloween is a traditional festival in the west, which falls on June 3 1 day every year. Many people in Asia mistakenly call Halloween Halloween. Halloween originated from the ancient Celtic New Year's Festival, and it was also a day to offer sacrifices to the dead. While avoiding the interference of evil spirits, they also offer food for ancestor worship and good gods who pray for a safe winter. The night before (that is, Halloween), children will put on makeup clothes and masks and collect candy from house to house.
