A Ming dynasty story collection records this proverb: "Rivers and mountains change easily; human nature does not."\p>
The phrase "江山易改本性难移" (rivers and mountains change easily, but human nature is hard to change) became one of the most commonly used Chinese proverbs. It acknowledges the stubbornness of character — the fact that people rarely change, even when they want to, even when they should.
江山易改，本性难移。
江山易改，本性难移。

Core Wisdom
You can reshape the landscape, redirect rivers, move mountains — but changing a person's fundamental nature is the hardest task in the world.
This proverb is both a warning and a comfort. As a warning: do not expect people to change their essential character. As a comfort: do not blame yourself for your nature — it is as fixed as the mountains, and working with it is wiser than fighting against it.
The comparison with "rivers and mountains" is significant: in Chinese thought, even the landscape is mutable (through floods, earthquakes, erosion). Human nature is portrayed as even more resistant to change than the physical world.
