Halloween, also known as All Hallows' Eve, is a holiday celebrated on October 31st in many countries around the world. This festive occasion has its roots in ancient Celtic traditions and has evolved over time into a modern celebration that combines elements of religion, folklore, and popular culture.

The origins of Halloween can be traced back to the ancient Celtic festival of Samhain. The Celts believed that on the night of October 31st, the boundary between the living and the dead became blurred. They would light bonfires and wear costumes to ward off malevolent spirits. Later, with the spread of Christianity, this festival was Christianized and became All Hallows' Eve, leading up to All Saints' Day on November 1st.

Today, Halloween is most commonly associated with trick-or-treating, where children dress up in costumes and visit neighbors to collect candy. Decorations often include jack-o'-lanterns (carved pumpkins), spooky figures, and haunted house themes. Parties and costume contests are also popular ways to celebrate.

In China, while not traditionally observed, Halloween has gained popularity in recent years, especially among younger generations who enjoy the fun aspects of dressing up and celebrating with friends.

万圣节，又称为诸圣节前夕，是在每年10月31日于世界许多国家庆祝的一个节日。这一节日起源于古代凯尔特人的传统，并随着时间的推移逐渐演变成一个融合了宗教、民间传说和流行文化的现代庆典。

万圣节的起源可以追溯到古代凯尔特人的萨温节。凯尔特人认为10月31日的夜晚是生者与死者之间的界限变得模糊的时候。他们会点燃篝火并穿上奇装异服以驱赶邪恶的灵魂。后来，随着基督教的传播，这个节日被基督教化，并成为诸圣节前夕，紧接着在11月1日便是诸圣节。

如今，万圣节最常与“不给糖就捣蛋”联系在一起，孩子们会穿上各种服装去拜访邻居收集糖果。装饰通常包括南瓜灯（雕刻的南瓜）、恐怖人物和鬼屋主题。聚会和化妆比赛也是庆祝的一种常见方式。

在中国，虽然传统上并不庆祝万圣节，但近年来随着年轻一代对这种乐趣的喜爱，它也逐渐流行起来。
