万里无云 (wàn lǐ wú yún) — (idiom) cloudless, clear and boundless sky

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

This origin belongs to the traditional form 萬; 万 is its simplified writing.

For 万, the form 萬 was originally a picture of a scorpion, later borrowed for its sound to write 'ten thousand'; the scorpion picture is unrelated to that number.

Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

This origin belongs to the traditional form 裡; 里 is its simplified writing.

The simplified 里 stands for more than one traditional character. In most words (里, 里面) it is 裡; in others (公里) it is 里 or 裏.

The form 裡 pairs 衤 (clothes) with 里 as a sound component.

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

This origin belongs to the traditional form 無; 无 is its simplified writing.

For the simplified 无, the story is about 無. 無 drew a person dancing with ox tails held in both hands to pray for rain, then was borrowed for 'have no', so the picture does not explain that meaning.

Two or more meaningful parts placed together so that their meanings combine into a new one.

This origin belongs to the traditional form 雲; 云 is its simplified writing.

The traditional form 雲 is 雨 (rain) plus 云; 云 was the original writing for 'cloud', and 雨 was added to separate it from the borrowed sense 'to say'.
