Rich
💰 富 = wealthy + 含 = contain; literally 'contains wealth' = rich in
富 means rich/wealthy and 含 means to contain or hold within. Together 富含 means 'rich in' or 'abundant in' — used for things containing a lot of something, like 富含维生素 (rich in vitamins).
富 — roof 宀 + one 一 + mouth 口 + field 田
Originally a pictograph of a tall jar full of grain or wine under a roof, symbolizing a household with abundant stores. The lower part 畐 depicted the full vessel and also gave the sound, while 宀 (roof) marked the home. Over time the meaning shifted from 'full vessel' to 'wealth, abundance, rich.'
含 — mouth 口 + 今 (jīn, phonetic)
含 is a phono-semantic compound. The 口 (mouth) component gives the meaning — holding something in the mouth — while 今 supplies the sound. From the literal sense of keeping something inside the mouth, it extended to mean 'contain', 'include', or 'hold within'.
