Repetition of ancient poems

Redundant repetition is not simple. There is a story in the ancient joke book: a poet wrote a poem "It's a matter to stay in a mountain house", in which he wrote: "The lonely monk returns alone, and Chai flies away and closes the door. In the middle of the night, the cuckoo cries. " He also wrote Ode to the Old Confucianism, which is also a four-line poem: "A scholar is a student and loves to sleep and snore. Shallow and barren, unlearned, the dragon declines in old age. " The enlightenment of these jokes is that it is ridiculous that this tautology causes a lot of redundant information. But there are many words like Li Qingzhao, with repeated sentences or words, which strengthen the feelings of the poet! For example: crossing, crossing. Got it, got it. Look for it, it's cold, wait!
