Xia dynasty introduction
Xia Dynasty (about 2070 BC ~ about 65438 BC+0600 BC) was the first hereditary dynasty recorded in China's history books. It is generally believed that after the Xia Dynasty spread to14th generation and17th generation, the founder was Kai, and Yangcheng (now Dengfeng, Zhengzhou, Henan) was its capital. According to historical records, Yu was originally passed on to Yi, but Yi gave way to Yu's son Qi. This period of history is regarded as the beginning of "home on earth" in the history of China.
Since the establishment of the Xia Dynasty, the tribes that changed their surnames in the Xia Dynasty 1 1 had a patriarchal clan relationship with the royal family in blood and a tributary relationship in economy, which roughly constituted the core territory of the Xia Dynasty. There are a certain number of bronze and jade ritual vessels in the cultural relics of the Xia Dynasty, dating from the late Neolithic Age to the early Bronze Age.
