The penalty configuration is the most controversial topic in the crime of prostituting girls under the age of 14. Compared with the crime of rape, no life imprisonment and death penalty are set. So it seems that the punishment of this crime is not severe enough, and thus leads to strong criticism by some people. If take a closer look, however, we will find that there are differences between this crime and the crime of rape in constituent elements. Besides, both basic behavior and aggravated behavior can get corresponding punishment in this punishment range. Thus, there is no need to match the punishment of aggravated crime of rape with the crime of prostituting girls under the age of 14. The existing penalty configuration can obtain enough rationality from the theory of interpretation according to the principle of balance between crime and punishment.
