Officials in the Dai family's faction weren't all upright. Some of them were corrupt and had broken the law too. The Yuan family and some other families had found out about it, but what they had done had nothing to do with the Dai family, so the Dai family wasn't really affected.
Yesterday, Pei Jiangchao was sentenced. Although it was an abduction, it didn't succeed and Dai Xiongyu wasn't injured. Therefore, he didn't receive a serious punishment. He was only sentenced to five years in jail and all of his properties were confiscated.
His properties would be public funds and he also had to pay Dai Xiongyu compensation. The Pei family decided to double the amount of money.
Although it was not really a huge amount for them and it couldn't do anything, it was still necessary, otherwise other people might think that the Pei family didn't need to pay a price for their mistakes.
