炎帝
China is one of the world's oldest and most complex civilizations, whose culture dates back thousands of years. Overseas Han Chinese maintain cultural affinities to Chinese territories outside of their host locale through ancestor worship and clan associations, which often identify famous figures from Chinese history or myth as ancestors of current members. Such patriarchs include the Yellow Emperor and the Yan Emperor, who according to legend lived thousands of years ago and gave Han people the sobriquet "Descendants of Yan and Huang Emperor" (; ), a phrase which has reverberative connotations in a divisive political climate, as in that of between Mainland China and Taiwan.
