Halloween is a western festival。 It’s on Oct。31st。 It’s a happy time for children because at night they put on the masks to attend the party。 After the party， they knock at someone’s door and say: “trick or tread”。 It means if you don’t give me the candies， I will play trick on you! At last kids can get enough candies for one year。
