一千九百万 (yì qiān jiǔ bǎi wàn) — 19 million (nineteen million)

An abstract idea shown by a mark or a diagram rather than by a picture of an object.

一 is drawn as one horizontal stroke, marking the number one.

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

千 pairs 人, whose sound was similar, with 一, a number stroke; the extra line was explained as extension, and a thousand is a number reached by extending counting.

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

The shape comes from a stylized hand bent at the wrist, with the lower-right hook showing the bend. Later, it was taken to show a tightened fist bumping up to ten, giving the number nine.

百 combines 一, which carries the number meaning, with 白, which provides the sound.

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.
