How He Got HIs Name

I said, Teacher Kao, why do you call yourself Dead Letter Kao? He sighed and put down his cup.
This is the story of Dead Letter Kao:

Iin his country he was a scholar, a teacher of the arts. The Change came and he was sent to a remote town to work in the communications office reading dead letters.
His job was to read these letters and find a way to post them to the people who they were meant for. He worked long hours. There wasn’t much light, warmth or comfort. He had a rickety old desk, a broken backed chair and an occasional cup of cold tea. There were many letters and he had to sort thru them to find where to send them.
I sat there, astonished, from a scholar to reading dead letters. What a tragedy. He smiled and said, “No, quite the opposite. I grew to know some of the people thru their letters. A lot of the letters I had to throw away, but I kept a few that touched my heart.”
He suddenly got up without a word and left. I thought I saw tears in his eyes before he turned away and left.
That was the story behind his name.
