The Story Behind 一叶障目
The Leaf That Blocks the View
The idiom 一叶障目 comes from classical Chinese philosophy, particularly from "He Guanzi" (鹖冠子).
The full phrase is "一叶障目,不见泰山" (A single leaf blocks the view, and Mount Tai cannot be seen).
It describes how a small thing (a leaf) can block one's view of something much larger (Mount Tai, one of China's most famous mountains).
The phrase teaches that focusing too much on small details can prevent us from seeing the bigger picture or understanding the whole situation.
