Who are the ancient poets who questioned the universe?

Qu Yuan. Tian Wen, the greatest romantic poet in China, is another long poem with strong Taoist color after Li Sao. It is also one of his representative works, which is included in The Songs of Chu edited by Liu Xiang in the Western Han Dynasty. The whole Tian Wen is Qu Yuan's inquiry about the phenomena of heaven and earth, nature and the world. Poems range from natural phenomena such as the separation of heaven and earth, the change of yin and yang, the show of the sun, the moon and the stars, to myths and legends, and even historical stories such as the rise and fall of sages and fierce wars, which shows Qu Yuan's bold questioning of some traditional concepts and his exploration spirit of pursuing truth. Tian Wen is a wonderful work in China's classical poetry circle, and it is known as "a masterpiece through the ages".
