The pines and pines are all walking nearby, and birds and fish follow them at every turn. It's a pity that we are separated by borders and cannot see our old friends. What's the meaning

According to my understanding: Ah, this is a poem by Zhang Jiuling.

The first two sentences are written about the environment, followed by emotion.

That is to say, there are pines and bamboos on both sides, poultry on the land and fish in the river (a typical rural environment, very nice.) Unfortunately, it is too far away and my friends can’t see it.

My level is a bit low, so I’ll make do with it.
