"Why is Dad a criminal?"
When children are little, they are often asked a question... do you like Dad or Mom more?
It's a question that is difficult to answer no matter what. Usually, children would say "I like both," but there are always people who want them to make a choice, and Hai Yunlan was asked this question as a child too.
"If I have to choose one, then it'd be Dad."
Hai Yunlan's father... was an extremely upright man, what you'd call a "good person."
But being a "good person" is not so easy. Especially in Heisong Town.
The people of Heisong Town taught their children: always be cautious, don't offend others lightly, and don't reveal your real name to strangers.
