See? This was the retaliation.
Chen Song and his men went to the riverbank to investigate and discovered the assailant's footprints. They weren't large, looking as if they belonged to a young, not-yet-fully-grown girl. By connecting this clue to people who held a grudge against Chen Wanyue and asking at the city gate about a woman in yellow who had left town that day, they easily identified the culprit.
The girl was surprisingly direct and confessed immediately. Her mother, however, collapsed to the ground in tears, insisting that her daughter had only acted at her urging and that she wanted to take the blame for her.
Of course, she couldn't take the blame for her daughter. The girl was now locked away in prison.
When Chen Wanyue learned the culprit had been caught, she even went to the prison personally to taunt the girl, saying she would bribe the death row inmates to torture her to death.
