What ancient poem does Silent Mourning in White come from?

From the constellation network: in the poem, "I don't forget the misty rain, I don't forget the dust, I don't forget the dream." Some people regard this as: the cool breeze blows away the teenagers here, and the white clothes are silent. If you laugh, you will be intoxicated. You will be happy all your life, dyeing Tsing Yi with ink, and never changing old people with youth. Laugh at Iraqis wearing red makeup. Iraqis laugh the most. Drink up this pot of bright moonlight, and the rest of your life will be too long for you to forget, lonely and unforgettable. It is also an extravagant hope to hurt her in a dream. shirt
