Liu Yuxi is famous as a poet, and his writing style is bold and heroic. Although he is often relegated to a bad life, he always maintains an optimistic attitude. Since ancient times, I feel sad and lonely every autumn. I think autumn is more than spring. There is no one in the clear sky in Wan Li, and a crane, Ling Yunfei, has aroused my meditation on the blue sky. These two poems have no traditional melancholy tone. Liu Yuxi doesn't think autumn is bad, but praises the spirit and scenery of autumn. Liu Yuxi is such a person. His positive attitude is not that the ignorant are fearless, the newborn calf is not afraid of tigers, nor is he forcing himself to comfort himself, but a rational positive attitude with insight into life. This spirit is more valuable and touching.
