Zheng Zhun in Tang Dynasty

Pieces of flying leisurely, the roof in front of the mountain.

Gone forever, revealing the clear sky in Wan Li.

This is the poet's description of the clouds in the sky. Clouds floated in Wan Li, silently, from Jianglou to piedmont, and never came back all day. The sun shines through the clouds, and a sunny tomorrow seems just around the corner. Since ancient times, people have yearned for the free cloud, hoping that they can be as leisurely as the cloud. Therefore, the word "leisure" in the first sentence not only describes the attitude of the cloud, but also reflects the poet's mood at that time.
