Origin

This character most likely started as a picture of something divided into four parts. The box-like shape (囗) appears twice, suggesting a contained space, and the component in the middle helps divide it conceptually. Over time, the Chinese writing system developed a simple enclosed shape with internal markings to represent the number four—a way of showing a complete group split into four equal sections. The modern form keeps this basic enclosed structure, making it easy to recognize as a distinct character for the number four.
