What is the ancient meaning of Chang 'an?

The ancient meaning of Chang 'an is a long seven-character ancient poem. It is the representative work of Lu, a poet in the Tang Dynasty, and also one of the representative works of Seven-character Songs in the early Tang Dynasty. The whole poem is divided into four parts, expressing the ancient meaning and writing the present situation, showing the broad picture of Chang 'an social life at that time. The poet used traditional themes to write his own feelings, claiming to be "one of the three outstanding orthodox religions", describing the real life scene in Chang 'an, Kyoto at that time, showing his love and yearning for a better life. It is ironic to write about the extravagant life and internal disputes of the elite; At the same time, it expresses loneliness and dissatisfaction, and also reveals the life philosophy of impermanence and prosperity. The theme and language of this poem are very close to those of Qi Liang Palace poems such as Xiao Gang's Five Qi Qu, but their thoughts and feelings are quite different. Although his words are rich and colorful, they do not hurt elegance. The writing of the poem is similar to that of Han Fu, which tries to spread the truth of the object of description, with a slight meaning of "persuading everyone to satirize one person".
