Abstract:
Generally speaking, the records of Yan Emperor and Shen Nong in ancient books have obvious stage characteristics, which can be divided into several stages:before the Warring States, Yan Emperor and Shen Nong were two different independents. The concept has strict boundaries, and the classics separately record the two; from the Warring States period, there are two phenomena of overlapping and partial overlap in the classics; the two Hans are the key period of integration, the Western Han Dynasty is mainly divided, and the two Hans begin to reverse. In the Eastern Han Dynasty, the fusion was the mainstream; during the Wei, Jin, Southern and Northern Dynasties to the Sui and Tang Dynasties, the two gradually merged and eventually fixed, forming a new concept of Yan Emperor Shennong, which has been used since the Tang and Song Dynasties. The gradual establishment of the concept of Yin Emperor Shennong is compatible with the political background and historical evolution of each period. The case of the integration of the two reflects the integration of ancient historical legends and the reconstruction of ancient history in the process of national integration.
