Each of the above has its own source. According to more than 100 ancient books and archaeological studies by experts listed in Wen Yiduo's Dragon Boat Festival Examination and Dragon Boat Festival History Education, the origin of the Dragon Boat Festival is a totem festival held by Wuyue people in the ancient south of China, earlier than Qu Yuan. However, for thousands of years, Qu Yuan's patriotic spirit and touching poems have been deeply rooted in people's hearts, so people "cherish it and mourn it, talk about it in the world, and tell it through the ages." Therefore, the theory of commemorating Qu Yuan has the widest and deepest influence and occupies the mainstream position. In the field of folk culture, China people associate dragon boat racing and eating zongzi on the Dragon Boat Festival with commemorating Qu Yuan. Many calligraphers in ancient and modern times were also moved by Qu Yuan's spirit and the romance of Li Sao, and created impressive calligraphy works for Li Sao.
