Some festivals are held to honour the dead or satisfy the ancestors，who might return neither to help or to do harm. For the Japanese festival Obon，people should go to clean graves and light incense in the memory of their ancestors. They also light lamps and play music because they think what this will lead the ancestors back to earth. In Mexico，people celebrate the day of the dead in earlily November. On this important feast day，people eat food in the shape of skulls and cakes with "bones" on it. They offer food，flowers and gifts to the dead. The Western holiday Halloween also has its origin in old beliefs about the return of the spirit of dead people. It is now a children's festival，which they can dress up and go to their neighbours' homes to ask for sweets. If the neighbours do not give any sweets，the children might play a trick at them.
