here is an example:

editpartA(figureA) ->modelelementA
editpartB(figureB) ->modelelementB
modelelementA and modelelementB are the same level emelents

how should editparts response when elementA becomes a child of elementB
(dragging figure into figureB)?

should i give up the old editparts and recreate all the editparts again?
if it's not the right way, how should i do?

You don't have to worry about creating/disposing editparts. When modelB
becomes a child of modelA, modelA should fire a notification. editPartA,
when it gets notified of this, should call refreshChildren(). If you've
properly implemented editPartA's getModelChildren() method, everything
should just work for you.
