In fact, Halloween is a ghost festival in the west, just like "July and a half" in China. They believe that on this day, the dead will come from Hell and Back, so the living will pretend to be monsters, so that no one can recognize anyone.
Now, in the form of celebration, the lights will be turned off at home everywhere, and then terrible scenes will be arranged. Children at home will also dress up as cute ghosts, knock on doors for candy, and say "trick or treat". The way to celebrate Halloween in China is to hold Halloween parties and dress up as ghosts to party together.
