Halloween, known as "万圣节" in Chinese, is a traditional festival celebrated on the night of October 31st. It has its roots in ancient Celtic traditions and has evolved over time into a popular cultural event around the world, especially in Western countries.

The origins of Halloween can be traced back to the ancient Celtic festival of Samhain, which marked the end of the harvest season and the beginning of winter. The Celts believed that on this night, the boundary between the living and the dead became blurred, allowing spirits to walk among the living. To protect themselves, they would light bonfires and wear costumes to scare away evil spirits.

Over the centuries, as Christianity spread throughout Europe, the festival was merged with Christian traditions. The day after Halloween, November 1st, became All Saints' Day, also known as All Hallows' Day. Hence, the name "Halloween" comes from "All Hallows' Eve," meaning the evening before All Saints' Day.

Today, Halloween is widely celebrated with various activities such as trick-or-treating, costume parties, pumpkin carving, and haunted house visits. Children dress up in costumes and go door-to-door saying "trick or treat," while adults enjoy themed parties and decorations.

In recent years, Halloween has also gained popularity in many non-Western countries, including China, where people are increasingly participating in the festivities for fun and entertainment.

Although the celebration may vary from country to country, the core spirit of Halloween remains the same: a mix of mystery, fun, and a touch of spooky atmosphere. Whether you're dressing up as a ghost, a witch, or a superhero, Halloween offers a unique opportunity to embrace creativity and enjoy the thrill of the season.
