What is a sentence that can't be written in poetry?

"You can sing even if you can't write a poem" said "Learn 3 Tang poems by heart". From Sun Zhu's Preface to 3 Tang Poems in the Qing Dynasty: "Read 3 Tang Poems well, and you can recite them even if you can't write poems." It means that as long as a person remembers many Tang poems and reads them thoroughly, he will certainly learn to sing and write poems. Three hundred Tang Poems is a widely circulated anthology of Tang poems. The 289-year Tang Dynasty (618 -97) was the golden age for the development of China's poetry. There were many famous poets, and the number of Tang poems was more than 5,. Sun Qin 'an's "6 Kinds of Summaries and Prefaces of Selected Poems of Tang Poetry" points out: "There are still more than 3 kinds of selected poems of Tang poetry that have been lost. Among them, the most popular and well-known is "3 Tang Poems".
