《晋书·志·第二十章》
五刑不能核实，就用五罚来补正，五罚不能治罪，就用五过来补正，本意不坏却做了坏事，用金钱赎罪。
五刑不简，正于五罚，五罚不服，正于五过，意善功恶，以金赎之。
The five punishments cannot be verified, so they are corrected with the five fines. The five fines cannot be punished, so they are corrected with the five commutations. The original intention is not bad but has done bad things, so they redeem the crime with money.
