What does it mean to say a good word about human nature, which is not unexpected and endless?

Tang-Du Fu-Talking about the value of water like the sea on the river Author: Tang Author: Du Fu Title: Talking about the value of water like the sea on the river: Talking about the content: For human nature, words are amazing and endless. Old poems are muddy and prosperous, but flowers and birds are not deeply worried about spring scenery. For fishing, a new water sill was added, so the boat was replaced by a raft. I hope that Tao Yuanming, Xie Lingyun and other poetry masters will definitely chat with each other and have a tea party. My quirk is that I especially like writing poems and sentences. If I can't write amazing words, I won't stop until I die. [Appreciation] These two sentences show that the poet attaches great importance to the choice and tempering of language in his poetry creation. He is good at making love. And think that if you want to write a sentence well, you must have enough surprising language. He pursues this language persistently and will never stop until he reaches his goal. The poet's deliberate pursuit of poetic language and serious attitude towards literary creation are one of the important conditions for him to become a great poet.
