- lit. set out and it becomes spring (idiom); to effect a miracle cure (of medical operation)

“bring back life to patients (said in praise of a good medical doctor); a touch of the hand brings back spring”
着手：动手。一着手就转成春天。原指诗歌要自然清新。后比喻医术高明，刚一动手病情就好转了。
Origin 唐·司空图《诗品·自然》：“俯拾即是，不取诸邻，俱道适往，着手成春。舅逢花开，如瞻岁新。”
