人生是什么？是舞台还是客栈，是拼搏还是旅行，是享乐还是苦役，是泡影还是永恒？自古以来，就有敏感的心智提出并试图回答这样的问题，可是迄今仍未见到一个公认的答案（也许根本就没有公认的答案）。如果说人生似谜，人们是否能窥见其谜底？如果说人生如梦，人们是否有梦醒 What is life? Is the stage or inn, is fighting or traveling, is pleasure or hard labor, is bubble or eternal? Since ancient times, sensitive minds have raised and tried to answer such questions, but so far they have not yet seen a generally accepted answer (there may be no generally accepted answer). If life seems mystery, people can glimpse the answer? If life is a dream, do people wake up?
