What does this poem mean?

The white clouds floating high in the sky cannot rise to the top of the mountain, so I dare to compete with them.

The sky-high mountains are endless, and the floating sunset glow is light and thick, bright and dark.

When we embark on our journey at dawn, we can see the bright moon hanging high in the sky through the gaps in the towering trees. It seems that as the mountain road twists and turns, the bright moon will jump out of the trees.

As the dawn gradually begins to dawn, the Milky Way gradually sinks westward and is obscured by the peaks again.
