Appreciate:

The whole article is Qu Yuan's questioning about the phenomena of heaven and earth, nature and the world. From the natural phenomena such as the separation of heaven and earth, the change of yin and yang, the sun, the moon and the stars, the poem has always questioned myths and legends, and there are also historical stories such as brave men and sages, the rise and fall of war, which shows Qu Yuan's bold questioning of some traditional concepts and his exploration spirit of pursuing truth.
