桃花庵歌 (明)唐寅

桃花坞里桃花庵,桃花庵下桃花仙。  桃花仙人种桃树,又摘桃花卖酒钱。

酒醒只在花前坐,酒醉还来花下眠。  半醒半醉日复日,花落花开年复年。

但愿老死花酒间,不愿鞠躬车马前。  车尘马足富者趣,酒盏花枝贫者缘。

若将富贵比贫贱,一在平地一在天。  若将贫贱比车马,他得驱驰我得闲。

世人笑我太疯癫,我笑他人看不穿。  不见五陵豪杰墓,无花无酒锄作田。


晚钟

by 洛兵

晚钟敲响从城市那边  飞来宁静的翅膀
有家的人请回你们的家  没家的人请走进那夕阳

晚钟敲响从夕阳的眼中  流出宁静的凄凉
爱我的人请过来一起唱  恨我的人请躲开那月光

晚钟敲响从新月的梦里  落下宁静的忧伤
生者依旧习惯地擦去泪水  逝者已矣请返回你们的天堂

晚钟敲响从天堂上面  传来星空的回荡
醒来的人请守好你们的梦想  沉睡的人请把一切遗忘
