The flame of hope has been extinguished again and again, and the poems include "There is no road to doubt after heavy mountains and heavy waters" and "Another village on Liu 'an".
Poetry is the sentence that makes up poetry. Poetry usually limits the number of words in each sentence according to its format. China's earliest poems were structured with metrical poems, and the metrical requirements were strict. For example, the poems in the pre-Qin period are generally four words per sentence, which can be found in the Book of Songs. Later, it developed into a five-character or seven-character rhythmic poem, which was found in Tang poetry.
