死去元知萬事空 Not until on my deathbed do I know everything is a void;

但悲不見九州同 the only regrettable thing is yet to see our nation reunited.

王師北定中原日 One day when my last wish comes true.

家祭勿忘告乃翁 in memorial dont forget telling the good news to your Dad. 

PS  A friend of mine emailed me this famous poem which, he thinks, may be similar to the one I posted yesterday.  BTW, it is impossible to see "王師北定中原日" any more， so I did it in paraphrase.  (Well, now the real situation is 西望王師又一年。）
