死
The fundamental fact about all of us is that we're alive for a while but will die before long.
We die. That may be the meaning of life. But we do language. That may be the measure of our lives.
The past is not dead, it is not even past.
时间是最好的老师，但不幸的是，它杀死了所有的学生。
Time is the best teacher, but unfortunately, it kills all its students.
