In the poem by
陆游 the plum blooms alone by a broken bridge and ends
零落成泥碾作尘,
只有香如故 'fallen into mud and ground to dust, only its scent stays the same'.
毛泽东 wrote that he had read it and
反其意而用之 'turned its meaning around': his plum smiles among the spring flowers,
待到山花烂漫时,
她在丛中笑 'when the mountain flowers are in full bloom, she will be laughing among them'.
