I found this aphorism in my book of Korean aphorisms.
높은 가지가 부러지기 쉽다
nop.eun ga.ji.ga bu.reo.ji.gi swib.da
be-high-PART branch-SUBJ break-NOM be-easy-INF
The high branch breaks easily.
This refers to the fact that the higher branches of a tree break more easily, and it’s a metaphor for how those who climb the highest socially experience the greatest loss when they fall. “The higher they climb, the harder they fall” seems the equivalent English language version.
