The criminal law of our country is full of plot crimes，and under the background of risk criminal law，from “Criminal Law Amendment（Ⅷ）” to “Criminal Law Amendment（XI）”，the legislation of plot crimes is expanding day by day by adding new charges，revising non-plot crimes，expanding the criminal circle，aggravating statutory punishment and other ways. Risk criminal law pays attention to safety and prevention，which determines that it has the negative side of weakening freedom，and needs to seek a rebalance between safety and freedom. And the plot crime has the function of enlarging the crime circle and limiting the crime circle，which is mutually contradictory and entanglement，which has the unique advantage in the value balance. In order to prevent excessive security and atrophy of freedom，the legislation of plot crime should hold the position of limiting risk criminal law and pay attention to the function of restricting crime circle. At present，there is still a gap between the legislation of plot crime and the above standpoint. From the perspective of systematization，it is suggested to set the plot crime within the scope of misdemeanor. And adopt the plot offense legislation mode of “listing”，strictly explain the plot elements，add the names of minor illegal crimes and other crimes，delete the names of felony crimes such as the crime of illegal production，trading，transportation and smuggling of narcotic substances，unify legislation on crimes of corruption and bribery and other measures.
