History of Halloween
There's a lot of history about the origins of Halloween, I did some research on the internt, and it turns out that most people agree that Halloween originated from the traditional Celts harvest festival. According to the legend, this day is haunted by “all kinds of ghosts, who will leave the underworld and wander around the world, visit their relatives and friends." This night is also particularly dangerous, thus, in order to scare away those evil spirits, people would wear masks and walk around the village, which then became the origin of mordern day Halloween dressing up tradition.
