Introduce a book, and after reading it, you will be very interested in studying history, which is the change at the beginning. Generally speaking, we think there is a gap between the modern history of China and the ancient history of China, but we can't deny that history still carries its thousand-year character today. Maybe we need to reflect on our social and historical views in order to see the dotted line between historical steps. Liu Qingfeng's Jin Guantao's book "Changes in Opening" aims to re-integrate the context of China's modern history with a view of social history that transcends the historical fracture. This book holds that there are two kinds of social ruling authorities. "The ruling authority of the social western democratic system comes from the rational spirit beyond a specific religion or ideology. People of different beliefs should abide by the common norms, so obeying the law and rules can be called normative identity. China's traditional ruling authority comes from ideological identity. China's social organization mode is the integration of ideology and social organization, that is, the only ruling ideology in society is the blueprint of social politics and economic organization, and social entities are the concrete realization of this blueprint. This social organization is the deep structure of China society, and it has become a historical unconsciousness in China culture. It has not really been realized in the century-long change. The essence of change is that tradition appears in a new form and has not been interrupted. In fact, this is the motive force to seek historical changes from the cultural and psychological level. Judging from this book, this explanation truly presents the integrity and systematicness of China's modern history.
