What is sadness? Write a poem as follows:
1. Sadness is a distant place that cannot be reached, and sadness is a hometown that cannot be returned.
2. Sorrow is the longing for relatives. I am here and my relatives are over there. Sorrow is the wind and rain in the heart. I am here, and the wind and rain are also here.
3. Sadness is worry about the future, sadness is loneliness and sadness, and sadness is self-pity.
4. Sadness is fog, sadness is mist, sadness is drizzle, sadness is a long night.
5. Sorrow is a softly sung ballad, and sorrow is a lingering mist.
6. Sadness is the looming clouds in the sky, sadness is the wind blowing in the ears, sadness is the moon at night, and sadness is the dream in the morning.
7. Sadness is the helplessness behind the smile, and sadness is the loneliness in the corners of the eyes and eyebrows.
8. Sorrow is the poetry flowing under your fingertips. You can see the beauty and feel the sadness.
9. Sadness is the passage of time, sadness is the passage of time. Sadness is the stubborn stone in the heart, and sadness is the lingering loneliness of the lingering smoke.
10. Sorrow is the endless cocooning of oneself, and sorrow is the indecision of being unable to move forward.
