Abstract: Civil self-help behavior is the right relief way for civil subjects to protect themselves when the situation is urgent and calls for timely public relief after the event. China's law does not stipulate this regulation， which leads to the lack of guidance on the civil self-help behavior of civil subjects in social life， and the lack of standards in the court's trial behavior. Civil self-help behavior serves as a civil rights relief way， which is a combination of public relief and private relief，and should be included in China's civil legislation. The constitution of self-help behavior， the civil public security force and the legal consequences should be clarified so as to guide and standardize civil subjects' self-help behavior， and entitle the individuals to the appropriate ways to achieve right relief and exert the unique functions of civil self-help behavior.

Key words: civil self-help behavior, public relief, private relief
