在野外，没有捷径。你必须为每一步付出努力。

We die containing a richness of lovers and tribes, tastes we have swallowed, bodies we have plunged into and swum up as if rivers of wisdom, characters we have climbed into as if trees, fears we have hidden in as if caves.

The only true voyage of discovery consists not in seeking new landscapes, but in having new eyes.

Sustainable development requires balancing economic growth with ecological protection.
