端午节，又称龙舟节，是中国的传统节日之一，通常在农历五月初五庆祝。这个节日有着悠久的历史，主要用来纪念伟大的爱国诗人屈原。屈原是战国时期楚国的一位大臣，他以忠诚和才华著称，但由于政治斗争而被流放。后来，当他得知祖国被敌国攻破后，悲愤交加，投汨罗江自尽。当地百姓为了保护他的遗体，纷纷划船到江中驱赶鱼群，并投粽子入水喂鱼，以免它们伤害屈原的尸体。

端午节的习俗丰富多彩。其中最著名的活动是赛龙舟，这是一种集体划桨竞赛，象征着人们奋力拯救屈原的努力。此外，人们还会吃粽子，这是一种用竹叶包裹糯米、豆类或其他馅料制成的传统食品。粽子的形状和口味因地区不同而各异，但都蕴含了人们对屈原的怀念之情。

英文介绍如下：

Dragon Boat Festival, also known as Duanwu Festival, is one of the traditional Chinese holidays celebrated on the fifth day of the fifth month in the lunar calendar. The festival has a long history and is mainly used to commemorate the great patriotic poet Qu Yuan. Qu Yuan was a minister of the State of Chu during the Warring States period. He was famous for his loyalty and talent but was exiled due to political struggles. Later, when he learned that his homeland had been conquered by an enemy country, he was so grief-stricken that he drowned himself in the Miluo River. Local people rowed boats into the river to drive away fish and threw zongzi into the water to feed the fish, so as not to harm Qu Yuan's body.

The customs of the Dragon Boat Festival are colorful. One of the most famous activities is dragon boat racing, which is a collective paddling competition symbolizing people's efforts to save Qu Yuan. In addition, people will eat zongzi, which is a traditional food made of glutinous rice wrapped in bamboo leaves with beans or other fillings. The shape and taste of zongzi vary from region to region, but they all contain people's memories of Qu Yuan.
