Phrases: 山顶（shān dǐnɡ）the summit of the mountain; 山谷（shān ɡǔ） mountain valley

这个字早期是由三座并排的山组成（ ），合起来就成了一座大山。后来为了方便书写，每一座山都用一笔来表示，变成了现在的“山”字了。

The earlier form was clearly a pictographic representation of three peaks standing side by side （  ）, creating the form and shape of a large mountain. Later, for the sake of convenience in writing, the peaks developed into single strokes.
