Abstract: The world has entered a period of turbulence and change, and international competition is increasingly embodied in the struggle of systems, rules, and laws. As the cultural dimension of the legal construction in China, the “second combination” mainly expounds that in the concrete practice, it is necessary to absorb the wisdom of traditional Chinese legal culture, combine the concept of socialist rule of law, and adhere to the Marxist methodology, so as to form a legal culture with Chinese characteristics. By condensing the common values of people-oriented, and giving full play to the cultural, developmental, and belief power of the legal culture, we will promote the continuous development of the legal construction in China. The longitudinal path to promote the coordinated development of three-dimensional dynamics, education, and communication theory is guided by inheritance and innovation, emphasizing the importance of legal publicity, making full use of digital and intelligent media, and promoting civilized exchanges and mutual learning of legal culture and thought. Integrity and innovation are the relationship of symbiosis and dialectical unity. Inheritance is for the better development of the legal construction, and innovation is the driving force. Comprehensively governing the country according to law is the inheritance of traditional legal culture, excavating the essence of excellent traditional legal culture, absorbing the concept of modern legal construction that keeps pace with the times, and internalizing excellent traditional legal culture as a lasting driving force for the legal construction in China.
