The mountains and rivers are full of tears, how long can they be rich and glorious? Today, we don't only divide water, but only autumn geese fly every year. Specific meaning

Seeing the mountains and rivers everywhere gradually made my clothes wet with tears, lamenting that wealth in the world could not last long. Now I'm the only one here in Fenshui (Fenshui should be a place name), just watching the geese fly by in autumn. Some of the words I wrote feel that life is short, the description of things is depressing, and I am helpless and sad about my feelings.
