使出最凶狠的手段

go with the flow; follow one's heart; do what one thinks is right

hang one's head

one and only

go to one'spost; go on duty

spare no effort; go all out; do one's best

small token of one's appreciation; small token of kindly feelings; a mere trifle

sweep before one's own door

within one's power;to the bes of one's ability( capacity)
