A china cabinet is the trickiest common furniture piece because it combines heavy wood with fragile glass. Splitting the hutch from the base and removing every glass shelf and pane is what keeps it intact.
Pro tip: A taped X on a glass pane does not stop breakage but holds shards together if it does crack, keeping everyone safer.
Watch out: Never move a china cabinet in one piece with the glass shelves or dishes still inside; the vibration alone can shatter them.
