1. Nostalgia is a cup of tea. This is a mediocre metaphor, but I like it very much.
2. Nostalgia is the endless sunrise and sunset.
3. Nostalgia is like a tree without annual rings that never grows old.
4. Nostalgia is a bright moon; homesickness is a deep sea.
5. Nostalgia is like the endless raindrops in the sky, like strands of silk, which are constantly cut and confused.
6. Nostalgia is like a crescent moon. Countless wanderers place their thoughts on it, hoping that the moon can help convey it.
7. Hometown is an old wine brewed by wanderers from millet. The farther away it is and the longer it is left, the more mellow the taste of the wine will be.
8. Nostalgia is the road ahead with no end.
9. Nostalgia is like a small stamp. I am on this side and my mother is on the other side.
10. Nostalgia is like a dense bamboo forest; nostalgia is like a strong aroma of wine.
11. Nostalgia is like a cloudless sky, stretching as far as the eye can see; when you grow old, nostalgia is like a letter without a stamp, buried in your heart.
12. Homesickness is like a strong cup of coffee, mellow but bitter; after leaving home, homesickness is like a sad and beautiful moonlight, pouring into the heart, deserted.
