In the period of social transition, social contradictions are more prominent and difficult problems emerge in an endless stream, and the pursuit of "external good" in criminal law system will inevitably lead to frequent legislative activities. Especially since the 1997 revision of the new Criminal Law of China, in a short period of twenty years a separate criminal law and nine amendments have been adopted to supplement and perfect its content. Implementing "violation of legal interests" as the basic principle of criminal legislation, inappropriate legislative provisions resulting from imperfection of legislative technology in a specific period should be decriminalized in time, thus to improve the criminal legislation technology and criminal law structure of China.
