After the incident, Chief Wang awarded Yang Ming a Good Samaritan certificate and twenty thousand yuan as a reward. Yang Ming wanted to refuse, but Chief Wang told him the money came from Province S' bounty, not from Song Jiang City Police Station, so it should belong to him.
Yang Ming opened a bank account and deposited all the bounty money in it since he didn't need the money now.
What made Yang Ming feel strange was: I had just killed a man last night, then how did the police find me this morning? How did they solve the case so fast? However, he understood the reason after he asked Zhao Ying. Zhao Ying was afraid that something bad might happen to Yang Ming, so she called the police while Yang Ming was fighting. Then the police followed her lead to solve the case.
As for the police's quick response yesterday, it was due to the same reason. The police came because Zhao Ying called them first.
