Apart from Confucius, who is the most famous ancient person in China?

Personally, I think foreigners are familiar with it except Confucius. Ancient China was Qu Yuan. Because it is because of him that the Dragon Boat Festival was held. Now more and more people live in China. They may be more interested in the traditional festivals in China, especially the activities of eating zongzi and racing dragon boats on the Dragon Boat Festival, which will make them feel very novel. At this time, they will want to know the origin of this festival and naturally know the character Qu Yuan.
