Mei's snow is white, but the snow has lost the fragrance of Mei. From Lu Meipo's "Xue Mei" in Song Dynasty: "Xue Mei refused to give up for spring, so the poet stopped writing and commented. The snow in Mei Xu Xun is three points white, but the snow has lost a plum. " It means that both plum blossom and snowflake think they occupy all the spring scenery, and no one will give in. It is difficult for poets to write critical articles. In all fairness, plum blossoms make snowflakes crystal white, but snowflakes lose to the faint fragrance of plum blossoms.
