Mausoleum of Huang Di
Yan Di allied with Huang Di in order to regain his lost territory in lower Yellow River from Chi You, a leader of Jiuli, a people from south China. Their combined strength proved advantageous for both, and they formed a merger.
The 'Three Huang and Five Di' are wise ancestral leaders of the country. They are revered similar to prophets in the Middle Eastern religions. 'Three Huang' refer to Fu Xi , Nu Wa, Shen Nong (Yan Di) while 'Five Di' refer to Huang Di, Zhuan Xiang, Di Ku, Tang Yao and Yu Shun.
The tempered Chinese national characteristics emerged after three subsequent dynasties: the Xia, the Shang, and the Zhou. The turmoil endured by people during the Spring and Autumn Period and the Warring States led to a common desire for a unified country.
Emperor Qin Shi Huang ruled as the first emperor, with Han tribes forming the nucleus of a united China. But the name Han is associated with the Western Han Dynasty that came after the first emperor's reign.
Another unsettling period arrived with the Three Kingdoms, Western and Eastern Jin, Northern and Southern Dynasties. The five hu people resettled in the Yellow River region. Then the Northern Wei reunified the territories to bring about peace. About this time the various minorities had tacitly acknowledged the dominance of Han people and their way of life. The Chinese nation had finally emerged.
