Tips
usage
Highlights the physical hardship of a long journey through rough terrain. Often paired with 跋山涉水 (cross mountains and wade rivers) for emphasis, or followed by a clause about what was achieved despite the effort.
memory
翻 (flip over) + 山 (mountain) + 越 (cross over) + 岭 (ridge). Each pair is a verb+landform: flip the mountain, cross the ridge. Two ways of saying the same thing, doubled for emphasis.
