Xi Changzhi could not recover from the shock at all. He wrote his father a letter and requested the latter to look into the matter.
Mr. Xi informed him of the outcome when he visited Xi Changzhi in prison.
"I've already questioned Mu Caiyi's parents, and they said that the person who ran her over back then is called Qiao Luo. Qiao An had indeed graduated from Northern Prefecture University. Mu Caiyi's parents were shocked to find out that you're still bearing a grudge even after so many years. They weren't willing to divulge anything at first, but they conceded after hearing that you had been put behind bars because of this."
