This book is an in-depth study on the criminal procedure in China. Using the social science research method, the author studies some systems and reforms, such as the criminal reconciliation, the sentencing procedure, the criminal incidental civil action, the trial hearing, the exclusionary rule and the defense system. The author puts forward some new theories and opinions. He points out that there are two modes of criminal procedure in China: the adversarial mode and the cooperative mode. He has advanced a new theory based on the practice of the procedure where the defendant pleads guilty or the parties reach a reconciliation. Also, the author has summarized three forms of criminal trial and three modes of criminal incidental civil action. He analyzes "conviction trial", "sentencing trial" and "procedural trial" and points out their defects. He holds that the coexistence of the three models of incidental civil action reflects some problems in the criminal procedure.
