西方情人节，即每年2月14日庆祝的节日，是全球范围内广受欢迎的爱情和浪漫象征。尽管这个节日在中国和其他亚洲国家也变得越来越流行，但其起源和文化背景却主要源自西方。

Valentine's Day, celebrated on February 14th each year, is a widely recognized symbol of love and romance across the world. Although this holiday has gained popularity in China and other Asian countries, its origins and cultural background primarily stem from Western traditions.

据传，情人节的起源可以追溯到古罗马时期。当时，2月被认为是净化和净化灵魂的月份，而基督教教会在这一时期纪念一位名叫瓦伦丁（Valentine）的殉道者。据说，这位瓦伦丁是一位牧师，他在公元三世纪时因秘密为情侣主持婚礼而被处死。他勇敢的行为和对爱情的支持使他成为后来情人节的象征。

It is believed that the origin of Valentine's Day dates back to ancient Rome. During this period, the month of February was considered a time for purification and spiritual cleansing, and the Christian Church commemorated a martyr named Valentine during this time. Legend has it that Valentine was a priest who was executed for secretly marrying couples during the third century. His courageous actions and support for love made him a symbol of what would become Valentine's Day.

现代情人节的主要活动包括赠送巧克力、鲜花和贺卡等礼物给爱人或喜欢的人。在这一天，情侣们通常会共度时光，表达彼此的爱意。此外，许多餐馆和酒店也会推出特别的晚餐和套餐，以吸引情侣们的光顾。

In modern times, the main activities on Valentine's Day include giving gifts such as chocolates, flowers, and cards to loved ones or those one admires. On this day, couples often spend time together and express their affection for each other. Additionally, many restaurants and hotels offer special dinners and packages to attract couples.

无论是传统的庆祝方式还是现代的习俗，情人节都已成为一个表达爱意的重要时刻。通过这一节日，人们不仅能够向心爱的人传递感情，还能重温那些关于爱与牺牲的美好故事。

Whether through traditional celebrations or modern customs, Valentine's Day has become an important moment for expressing affection. Through this holiday, people not only convey their feelings to their loved ones but also revisit the inspiring stories of love and sacrifice.
