Poetry. Liu Yuxi was a writer and philosopher of the Tang Dynasty. He was nicknamed Mengde and was known as a "poetry hero". Together with Liu Zongyuan, he was known as "Liu Liu", and with Bai Juyi, he was known as "Liu Bai". Liu Yuxi is known as a "poetry hero" mainly because his poetry style is bold and unrestrained, and has high artistic value. Liu Yuxi's poetry has a wide range of themes, involving politics, history, philosophy, life and other aspects. His works are heroic, profound in artistic conception and beautiful in language, showing his profound thinking about life and concern for social reality. Therefore, Liu Yuxi is known as a "poetry hero", which is a high evaluation of his artistic achievements in poetry. For example, "The Inscription on a Humble Room" is one of Liu Yuxi's most famous works, in which "The mountain is not high, if there are immortals, it will be famous. The water is not deep, if there is a dragon, it will be spiritual. This is a humble room, but I am virtuous." The meaning is: The mountain is not high. It doesn't matter how high it is, as long as there are immortals living in it, it will be famous; it doesn't matter how deep the water is, as long as there are dragons hiding there, it will be famous. Although this is a humble room, it is filled with fragrance because of my noble moral character. Through the description of the shabby house, it expresses the author's life interest and noble sentiments that he does not admire glory and is content with poverty.
