What does it mean to see Shui Han thin when the leaves fall in late autumn?

When the leaves fall in late autumn, I see bleak mountains and rivers and cold running water.

"Cold mountain" means that the mountain gives people a cold feeling and also means loneliness. In ancient times, "thinness" meant desolation and misery.

Cold mountains and fine waters are used to describe the barren land.

Cold mountains and thin waters can also describe a person's inner loneliness.
