A poem describing reunion after a long separation reminds me of an ancient poem. I wonder how to say it.

Poems expressing reunion after such a long separation are:

1, it is almost as difficult for friends to meet each other as the stars in the morning and evening. Tonight is a rare event, and this lamp is candlelight. -"To Wei Ba Chu Shi" Du Fu in the Tang Dynasty

Interpretation: It is really rare for close friends in the world to meet, just like one after another. What day is it tonight? I'm lucky to tell you the truth.

2. It's a beautiful scenery in the south of the Yangtze River, and you meet your husband when the flowers fall. -"Meet Li Guinian and Go to the River" Du Fu in the Tang Dynasty

Interpretation: It is the late spring season in the south of the Yangtze River. I didn't expect to meet your old acquaintance at this time.

We met here after ten years' separation. -"Farewell to the Ridge for a Long Time" Quan Deyu in the Tang Dynasty

Interpretation: Ten years ago, we separated and met in a long journey.

We talked and laughed, just like before, except that our hair is a little gray now. -"Huai Shang Wen Liang You" Wei Wu Ying in Tang Dynasty

Interpretation: Laughter and laughter are still the same as before, but unfortunately, their temples have turned gray.

The first time I heard your last name, I thought you were a stranger. Then I heard your name, and I remembered your young face. -"A brief but happy encounter with my brother-in-law" met by chance, just for parting ""Tang Dynasty Li Yi?

Interpretation: after ten years of separation, I suddenly met in different places when I grew up. I was surprised when I asked your name for the first time. I didn't remember my old face until I said it.
