In the rural governance system, self governance, law governance and moral governance are not in parallel relations. Self governance is the goal pursued by law governance and moral governance. Law governance is the guarantee for self governance and moral governance, and moral governance is the basis of self governance and law governance. The construction of "Three Governances Combined" in the rural governance system is conducive to the modernization of the country's governance system and governance capabilities, to the all-round implementation of the rural revitalization strategy, and to the satisfaction of the people's aspirations for a better life. To build a rural governance system combining three forms of governance, we need to strengthen the leadership of the Party, to base on the goal of building a self governance system, and to promote the construction of law governance and moral governance in rural regions, so that the three governance approaches can cooperatively contribute to the rural governance.
