What poem does "Flying Flocks and Falling Flowers" come from?

"Residual leaves and flowers, flying catkins falling".

1. Flowers float and water flows. Past feelings, yesterday's injuries, heartbroken places, leaving a touch of sadness. Where the flowers fall, where the wind blows, the city flies. There are withered grass and roots in the mountain, and flowers are everywhere. I can't bear to climb, but it's broken, and the flute sounds like nothing, making a mess.
