Honesty is the traditional virtue of the Chinese nation. Based on the classic social classification of the “acquaintance society” and “stranger society”, the integrity can be classified into “ethicaltype credit” and “legal credit”. At present, China's society is facing a very serious crisis of honesty and credit crisis, the historical transition of contemporary Chinese society constitutes the deep soil of social credit crisis of China, however, the social transition causes the absence of the system, which is the key factor in the crisis of credit. In the process of the transition from traditional society to the modern society, we should make full use of the basic role of the rule of law in the reconstruction of honesty and integrity, let “integrity of legal type” become the direction of the reconstruction of contemporary Chinese credit and studiously construct legal social credit system.
