"The snow in Mei Xu Xun is three points white, but the snow loses a piece of plum fragrance" means that plum blossoms make the snowflake three points crystal white, but the snowflake loses to the faint fragrance of plum blossoms. Plum blossoms and snowflakes have their own characteristics, and their contradictions are also quite special.
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-character poems, 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. After the further development of economy and culture in Song and Yuan Dynasties, the content of poetry was gradually expanded and deduced. In the later period of the new-democratic revolution, poetry evolved into a free poem that was not limited by the number of words.
