What does it mean to be stranded by years and lonely by life?

Let the viewer deeply realize that "in such a cool scenery, time is stagnant and life is lonely".

I think it's a situation that makes people feel relaxed and happy, time seems to be still, and there is only me and nature between heaven and earth, which makes people feel lonely. My favorite sentence is that a boat is moored in the depths of the reed flowers thousands of miles away from the cold color, which I think is similar to this scene.
