The word "劫富济贫" is formed by directly combining two verb-object phrases: "劫富" (rob the rich) and "济贫" (aid the poor). The characters are ordered sequentially, where the action of plundering from the wealthy ("劫富") is intrinsically linked to the action of assisting the impoverished ("济贫"), resulting in a compound term that denotes the concept of taking from the rich to give to the poor.
