These five poems contrast the eternity of nature and the vicissitudes of human beings, and express the feeling of nostalgia for the past and sighing for the present. The whole poem vividly shows that with the evolution of history, the prosperity of the nobles in the six dynasties palace has become a thing of the past, and there are both sympathy and allegory for the decline of emperors and princes who plot power. Poetry is the artistic treasure of Tang poetry, which integrates emotion, scenery, events and reason, and has a broad scene and profound meaning.
