If you say the lineup of your family members that have lived on this earth under the sun, you're really explaining your genealogy.

This kanji has a second meaning too. It means score, as in a musical score or sheet music. So if your sheet music says the line up of chords, especially sunnny notes, that's the score of a song. Those sunny notes are loved by your ancestors.

If you can't tell the difference between your genealogy and a musical score, you're a fool (ふ) and I can't help you. You aren't a fool, are you? You know the difference.
