"Treaty",frequently appearing in historical materials of the pre-Qin and Qin-Han dynasties,can be roughly divided into national treaties,military treaties,and private treaties according to their nature and content,which basically cover all aspects of social relations and national governance,regulating the country order at that time.In the early country governance,the moral norms represented by"treaty"have long served as important supplements to the order beyond the law,and also played the role of"common law".Some"treaty"even became an eternal"ancestral system"after the establishment of the unified state.The"treaty"laid the foundation for the formation of China's early national ideology and early moral culture by constraining in advance some possible future behaviors of both parties.With the continuous improvement of the unified national system,"treaty agreements"have been gradually replaced by specific written laws and regulations,while some of them,with strong moral and ethical norms and marked stamp of politics and morality,have also become part of the laws and regulations.
