It means: mountains overlap with water. I was wondering, there was no road ahead, and suddenly a colorful mountain village appeared. This sentence has now become a famous sentence through the ages. Now I am described as having encountered difficulties, and suddenly I saw a solution to the problem or difficulty, and I was overjoyed.

(Song) Lu You
Don't laugh at farm wine,
Raise enough chickens and dolphins in good years.
The rivers and mountains may change, but not one's essential nature
There is also a village.
Xiao and the drum follow the Spring Club.
Dress simply and keep the ancient customs.
From now on, if you want to take a leisurely ride on the moon,
Knocked on the door all night with a stick.
