Zhang was the picture of despair the first time I met him.
He had accidentally delivered a package to a neighbor of mine who took it and would not give it back. Now, trembling, he wanted to personally reimburse me for the lost item.
I refused to take his money, but for two days, he called me nonstop to apologize. At the time, I did not understand why he was so repentant. Then I found out how closely monitored — and severely punished — delivery workers like him are.
