It is easier to say the meaning of Dragon Boat Festival in English.

In the mountains, I also heard that the Dragon Boat Festival is to commemorate the patriotic poet Qu Yuan. It turned out that Chu Yuan was a doctor and a loyal man, but he was framed by a traitor and could not defend his country. In order to show his loyalty and arouse the patriotism of Chu people, Qu Yuan jumped into the river to protest. People are afraid that Qu Yuan will eat big fish, so they make many big rice balls. The big fish wants to stick the big fish's mouth so that it can't eat Qu Yuan. Later, people designated this day as Dragon Boat Festival to commemorate Qu Yuan by eating zongzi.
