In western countries, October 31 is "Halloween night". Halloween is a traditional festival in western countries. Festival night is the most haunted night of the year, so it is also called "ghost festival". It was believed that the spirits of the dead would return to their homes on this day to search for living things, and to regenerate, and that it was the only hope of regeneration after death.
It was a happy time for the children to spend Halloween together, and their faces were full of happy smiles.
