What is the original text of the poem "Flowers are not flowers and fog is not fog"?

Flowers are not flowers (Bai Juyi)

Flowers are not flowers, and fog is not fog.

Come in the middle of the night and leave at dawn.

When did a short and beautiful spring dream come?

Disappear like a cloud and can't find a place.

To annotate ...

Chaoyun: This is an allusion borrowed from King Xiang of Chu's dream of Wushan Goddess. Song Yu's preface to "Gao Tang Mi" says: My concubine is in the sun of Wushan, the maggot of the high hill, and it rains in the morning and evening, under the balcony.
