南柯一梦人去楼空
[nán kē yī mèng rén qù lóu kōng]
Nan Ke Yi Meng Ren Qu Lou Kong refers to An ephemeral Dream when people gone leaving empty houses. It comes from an ancient Chinese story about a brief but wonderful dream where one achieves glory but eventually awakens to a reality of disappearance. Hence it reflects on how transient the success and luxury are in life.
