“沉鱼”“落雁”“闭月”“羞花”的来历

沉鱼 春秋时期，越国有一个叫西施的，是个浣纱的女子，五官端正，粉面桃花，相貌过人。她在河边浣纱时，清彻的河水映照她俊俏的身影，使她显得更加美丽，这时，鱼儿看见她的倒影，忘记了游水，渐渐地沉到河底。从此，西施这个“沉鱼”的代称，在附近流传开来。

落雁

至于“落雁”，就是昭君出塞的那段故事。汉元帝在位期间，南北交兵，边界不得安宁。汉元帝为安抚北匈奴，选昭君与单于结成姻缘，以保两国永远和好。在一个秋高气爽的日子里，昭君告别了故土，登程北上。一路上，马嘶雁鸣，撕裂她的心肺，悲切之感，使她心绪难平。她在坐骑之上，拨动琴弦，奏起悲壮的离别之曲。南飞的大雁听到这悦耳的琴声，看到骑在马背上的这个美丽女子，忘记摆动翅膀，跌落地下。从此，昭君就得来“落雁”的代称。
