Some Chinese phrases paint such a vivid picture you don't need a backstory.
Like this one:
"Hand in hand" (手把手 shǒu bǎ shǒu)
But it doesn't mean actually holding hands.
Break it down:
手 (hand)
把 (grip)
Literally, one hand gripping another hand.
It means guiding someone closely and patiently, as if your hands are literally on theirs.
Use it for: Any detailed, hands-on instruction where you're walking someone through something in real time.
Example:
He sat with me and walked me through every single step. 他手把手地教我,一步一步来。
