Flowers are not flowers, fog is not fog, come at midnight and go at dawn. Come like a spring dream, go like a floating cloud. Whose poem is this?

Flowers are not flowers, and fog is not fog: I like flowers, not flowers; Say like fog, not fog. How long: It means that the party is too short. Chaoyun: Song Yu's "Gao Tang Mi" said: King Xiang of Chu and Song Yu swam to Yunmengtai, looked up at the Tang Dynasty, and saw clouds in the sky. Song Yu said it was Chaoyun. Xiang Wang asked Chen Yun what it was, and Song Yu replied: The former king tried to swim in Gaotang, and he slept in his spare time. He dreamed that a woman was leaving, saying: My concubine was in Wushan, the sun was shining, the high hills were blocked, it was raining at dusk, and she was under the balcony. Nowhere to find: because floating in the clouds, there is nowhere to find. This is a love poem, a hazy love poem. When I started reading, I didn't know what to say, but I felt an ethereal and blurred image flash by. It dawned on me at last that a woman had come to meet me. The first two sentences vaguely describe the scene at that time. What does this scene represent? The author didn't say. Three or four words: come in the middle of the night, leave at dawn, who will come and go? Still don't get it. In the last two sentences, the elusive original intention is revealed by means of notation. Poetry is really ethereal and elegant, subtle and graceful, giving people a hazy beauty. And there is a touch of sadness between the lines. Later generations used flowers instead of flowers as phonetic names. The whole poem was set to music and widely sung.

The fog is so thick that it smells like time flies. It's time around you. You can see it and seem to touch it, but you can never catch it.

Is to bring people into a fog as short as a spring dream; I am surrounded by flowers, but everything may be fleeting, replaced by thorns.
