The festival is divided into Dragon Boat Festival, which is said to be Qu Yuan.
I can laugh at the emptiness of the Chu River, but I can't wash it straight.
Translation:
Where did the Dragon Boat Festival come from? The legend of predecessors is for Qu Yuan, a doctor of Chu State. Ironically, the vast sea of smoke can't wash away the grievances of loyal people.
Extended data:
Dragon Boat Festival, according to legend, is the day when Qu Yuan, the first great man in China, committed suicide. Later generations wronged him and died. In particular, he threw zongzi into the river for sacrifice and rowed a boat to save him, thus forming the custom of solar eclipse and dragon boat race on the Dragon Boat Festival.
The author's quatrains put forward a thought-provoking question: despite all kinds of praises and sacrifices of later generations, tragedies like Qu Yuan's sinking into the river still happened after all, and such grievances cannot be simply washed away. This poem is profound, concise and powerful.
