The trees in the garden are lush, and the crystal dew rises in the sun.

Spring fills the earth with hope, and everything presents a scene of prosperity.

I am always afraid that when the cold autumn comes, the trees in Ye Er will turn yellow and the grass will wither.

The river runs to the sea, and when will it return to the west?

A lazy youth, a lousy age.

Introduction to the work:

Yuefu in the Han Dynasty was originally an official position in charge of music in ancient times. There was a "Yuefu Order" in the Qin Dynasty and Gengdi in the Western Han Dynasty. The Yuefu in the period of Emperor Wu of the Han Dynasty was large in scale, and its function was to take charge of the music used in the court and collect folk songs and music. After Wei and Jin Dynasties, all poems sung by Yuefu organs in Han Dynasty were called Yuefu poems.

The basic principle of Han Yuefu's creation is "feeling sad and happy, starting from things" (Art History and Literature awarded by Han Dynasty). It inherits the fine tradition of realism in The Book of Songs and reflects the social reality of Han Dynasty extensively and profoundly. The most outstanding artistic achievement of Han Yuefu lies in its narrative. Secondly, he is good at selecting typical details and expressing his character through his words and deeds. Its forms are five-character, seven-character and miscellaneous words, and it is particularly noteworthy that a number of mature five-character poems have been produced in Han Yuefu. The vast majority of Yuefu poems handed down from the Han Dynasty have been included in Yuefu poems compiled by Guo Maoqian, a Song Dynasty poet.
