History tradition and reality state of the nation decision conditions of China’s Civil Code is the inevitable trend of civil legislation, but《German Civil Code》, the representative of the “total-cent” compile mode, with General civil code plait commander-in-chief property law and identity law of the t Pan Deke swallow system, is not the best option. On the contrary, because the property law and the identity law of the different legislative principle-- real and credit in accordance with the legal effect of law is similar to the principle of the Construction, law of domestic relation of the facts of life is based on similar principles of the Construction, General Civil Code does not apply for domestic relation law, As property relations as the essence, cheaper, purpose, the combination is a result of accidental combination of motives, and the status of identity relations is a natural, inevitable, and the combination of nature, a kind of society that have to combine relation. The body, contents of the corpus, guest of property relation and identity relation and the main legal fact which caused property relations and the status of identity relations-- property behavior and identity behavior, there is a significant difference, so it is difficult to establish “Common provisions” between property law and identity law. Since the General Civil Code is actually a property laws General, the basic law can not be applied to identity law, and identity law in modern law is an important part of civil law. Therefore, not establish a gengral provisions and change to establish a preface plait may be a valid path out of Pan Deke swallow contradictions inherent in the system.
