Characters in this word

A drawing of the thing itself, worn down over three thousand years into a few strokes.

This origin belongs to the traditional form 長; 长 is its simplified writing.

The traditional form 長 pictures an old man with long hair. The simplified 长 is a later shorthand, so its strokes do not show that original picture.
