There is more than one form of democracy. Democracy is diversified, so is deliberative democracy. Chinese deliberative democracy is a great creation realized by the Communist Party of China on the basis of its practice of leading in the country's revolutions, constructions, and reforms. The earliest form of Chinesedeliberative democracy was the inter-party deliberative democracy, which was developed in its theory and practice from the united front to the multi-party cooperation, the inner spirit of which was to pursue consensus while recognizing the equal status of different parties and to create a win-win situation via communications and negotiations. It reflected the ideas of consultation and democracy that were consistently implemented by the Communist Party of China and resulted in the formation of inter-party deliberative democracy. The inner-party deliberative democracy was practiced in correspondence to the inter-party deliberative democracy. As the important performance of the inner party democracy of the CPC, it took shape from the practiceof the policies from following the mass lines to practicing people's democracy, in the process of which, to make the people as the masters of the country was taken as the preferred values, which in turn became the foundation of the inner-party deliberative democracy in many perspectives. Social deliberative democracy was started in the social transformation after the establishment of the new China and was moved forward in the second social transformation actualized by the socialist reform and development. Especially sinceChina's reform and opening-up policy, when the social relations and the social structure have undergone major changes, to deal with and to coordinate the conflicts among various interest groups and to meet the needs of the times, the Communist Party of China has infiltrated deliberative democracy from the politics to society and therefore has further promoted the formation of the social deliberative democracy. In the 21st century, with the deepened reform and opening-up policy, the contradictions among various sectors of the society are unprecedentedly intense. In order to coordinate the complicated and complex interest relations, the Communist Party of China creatively extends the deliberative democracy to the field of public affairs, advocating equal dialogues and negotiations for the harmonious coexistence of various interest groups and for the dynamic unity of a diversified society, promoting the formation of the public deliberative democracy. In short,in the history of its development from the united front to multi-party cooperation, from following the mass line to people's democracy, in dealing with and coordinating the conflicts among various interest groups, in learning from history and bringing forth the new ideas, the Communist Party of China has realized step by step the inter-party, inner-party, social and public deliberative democracy. Among the four forms of democracy, the first two extend horizontally, focusing on the political negotiations. While the political, social, and public deliberative democracies extend vertically and hierarchically, demonstrating a logic deepening from the nation's political level to the nation-society interaction level, and then to the nation-society-citizen interaction level. Chinese deliberative democracy is one of the important results of the localization of Marxism in China, is a significant form of the socialist democracy with Chinese characteristics, and is a unique contribution to the civilization of human democracy.
