What was the whole poem,"I can't see all the red cherry blossoms, and I paint the pear blossoms and tears on my clothes"?

This poem was written by the Tang Dynasty poet Bai Juyi,'Farewell to the Ancient Grass.' The whole poem is as follows: The grass on the plain withers and thrives once a year. The wildfire never ends, and the spring breeze blows, it grows again. The far-off fragrance encroaches on the ancient road, the clear green connecting the deserted city. And send the king's grandson away, full of parting feelings. When the red cherry blossoms have fallen, you can't see the tears of pear blossoms painted on my clothes. If life is only like the first time, what is the autumn wind sad painting fan? It is easy to change the heart of an old friend, but the heart of an old friend is easy to change. The words of Mount Li are gone. In the middle of the night, tears fall and bells ring. I don't complain. How can it be like the wish of a young man in brocade to be together?
