清明节是中国传统节日之一，起源于古代中国的祭祖文化。在每年的农历三月初三或四日，人们会前往祖先墓地扫墓，为已故亲人祭奠，祈求祖先保佑家庭平安。此外，清明节还有踏青、插柳、赏花等习俗，是一个重要的春季节日。

The Qingming Festival is one of the traditional Chinese festivals, originating from the ancient Chinese culture of ancestor worship. On the 3rd or 4th of the third lunar month each year, people go to the cemetery to sweep the tombs, mourn for their deceased loved ones, and pray for the blessings of their ancestors. In addition, there are also customs such as spring outings, planting willows, and appreciating flowers during the Qingming Festival, making it an important spring festival.
