据古文献考知炎帝比黄帝高一辈,时为二头君长制,炎帝主政,黄帝掌军,炎帝年老即当让位,旧称禅让;但出现异常情况。后来黄帝利用武力集大权于一身,达到大一统。 According to the ancient literature, Yan Yandi was a generation older than the Yellow Emperor, when the two monarchs, Emperor Yandi dominated the Yellow Emperor’s army, and Yan Emperor’s elders resigned as the old saying of letting go. However, there were unusual circumstances. Later, the Yellow Emperor took advantage of the power of armed forces in one and achieved unification.
