How do you explain that there is no doubt that there is no road and there is another village?

There is a famous saying, "There is no doubt about mountains and rivers, but there are other villages in the dark." From the Southern Song Dynasty poet Lu You's Tour of Shanxi Village.

This poem is about the scenery along the mountains and rivers, which contains philosophy and has been widely quoted for thousands of years. "There is no doubt about mountains and rivers, and there is another village." After reading such a fluent, beautiful, cheerful and lively poem, it seems that you can see the poet strolling among the green mountains, the clear mountain springs gurgling in the winding streams, the vegetation becoming more and more lush, and the winding mountain roads becoming more and more difficult to identify. When I was at a loss, I suddenly saw the flowers flickering in front of me, and several peasant cottages were looming among the flower trees, and the poet suddenly felt suddenly enlightened. The degree of excitement can be imagined.

The literal meaning of this poem is: there is no way out. Suddenly, I saw a village in front of me, where there were dark green willows and bright colors.

This poem was later extended to: from adversity to hopeful prosperity; When I was desperate, I saw the light ahead; Things took a new turn in despair;
