The Chinese word 卷土重来 is formed by sequentially combining four characters: 卷, meaning to roll or stir up; 土, meaning earth or dust; 重, meaning again or anew; and 来, meaning to come. Literally, it translates to "roll up the dust and come again", which graphically depicts an army advancing and raising dust upon returning, thereby metaphorically representing the concept of making a comeback or resurging after a setback.
