冤各有头，债各有主

冤有冤头，债有债主。谓事出各有对头，与他人无关。《京本通俗小说·错斩崔宁》： “我虽是个剪径的出身，却也晓得冤各有头，债各有主。”元末明初·施耐庵、罗贯中 《水浒全传》第二十六回：“小子粗疏，还晓得 ‘冤各有头，债各有主’，你休惊怕，只要实说。” 又，第六十六回：“晓谕居民，勿得疑虑： 冤各有头，债各有主，大军到郡，自有对头。”丁玲 《太阳照在桑干河上》 二五：“旁边的人便附和着胡立功的话：‘是呀！ 你们冤各有头，债各有主，各算各的，不就结了？’”

every wrong has its cuthor(/avenger/cause/doer/instigator) and every debt its incurrer (/debtor/creditor/lender); the culprit must pay for his wrong,the debtor for his debt
❍ 小子粗疏，还晓得 ‘～’。(《水浒全传》322) I am a rough fellow,but still I know ‘a wrong has its instigator,and a debt has its lender.’/～，大军到郡，自有对头； ……(《水浒全传》821) We say that each wrong has its avenger and every debt has its creditor,and promise that when our army enters Daming we’ll seek out only certain specific enemies.
❍ 冤有头，债有主，我自己没求过他们，要你去求求？(曹禺《日出》4幕)Every grievance has its incurrer and every debt its debtor. I didn’t go and plead with them myself,so why must you plead with them?/说得出这种无赖腔调的，未必懂得“～”的道理； 他们的行径一定是横冲直撞，乱来一阵。(叶圣陶《倪焕之》153) The ones who might speak in this ungentlemanly tone of voice would not be likely to appreciate the saying that “every wrong has its author and every debt its incurrer”； theirapproach would undoubtedly be direct and indis criminating.
❍ 不干你的事！冤有头，债有主！到后面去罢，不许乱跑！ (茅盾《子夜》118) It’s nothing to do with you. They’re the ones who’ve done wrong and they’ll have to suffer for it,not you. Now get in the back,and don’t go rushing about.
