It aimed at preventing litigation masters from monopolizing lawsuits and cheating the masses. A careful study was made in the essay on Guandaishu”origin,their participation in the lawsuits, the Cuoji, the papers, the incomes,their life in the society and the end of Guandaishu. Guandaishu played a part in making a lawsuit and maintaining the social order,but its original meaning changed in the process of operation because there was no difference between Guandaishu and lawyers and Guandaishu was cancelled in the end.However,it promoted the system of lawyers of the Republic of China.
