情人节的来历可以追溯到古罗马时期。相传在2月14日，罗马帝国时期，有一位名叫瓦伦丁的牧师，他因反对当时的皇帝克劳狄斯二世的命令，私自为士兵们举行婚礼，因此被捕并处死。据说，在他被处决前，他写了一封情书给他爱的女人，信上签名为“你的瓦伦丁”，这也被认为是情人节情书的起源。

情人节的传统在中世纪时期开始流行，人们会把自己的心意通过精美的情书和礼物表达给所爱之人。到了19世纪时，情人节的贺卡制作开始盛行，人们开始用各种方式庆祝这个浪漫的节日。

今天，情人节已经成为一个全球性的节日，人们在这一天会送花、巧克力、礼物等来表达自己的感情。无论是情侣之间的庆祝，还是家人、朋友之间的祝福，都传递着温馨和爱。

The origin of Valentine's Day can be traced back to ancient Rome. Legend has it that on February 14th, during the Roman Empire era, there was a priest named Valentine who opposed the emperor Claudius II's order and secretly held weddings for soldiers. He was arrested and executed. Before his execution, he wrote a love letter to his beloved woman, signed as 'Your Valentine,' which is also considered the origin of Valentine's Day love letters.

The tradition of Valentine's Day began to popularize in the Middle Ages, and people would express their feelings through exquisite love letters and gifts. In the 19th century, Valentine's Day card making began to flourish, and people began to celebrate this romantic holiday in various ways.
