How to remember?
It is like the gesture used when you are showing people you have eight apples or eight whatever. You put out your hands, showing people all your fingers except for the thumbs, as illustrated above.
This Kanji itself is a radical.
Do not confuse this Kanji with:
人-which means "human", "person"
入-which means "enter"
