商汤
The greater Luoyang area has been sacred ground since the late Neolithic period. This area at the intersection of the Luo River and Yi River was considered to be the geographical center of China. Because of this sacred aspect, several cities – all of which are generally referred to as "Luoyang" – have been built in this area. In 2070 BC, the Xia dynasty king Tai Kang moved the Xia capital to the intersection of the Luo and Yi and named the city Zhenxun (). In 1600 BC, Tang of Shang defeated Jie, the final Xia dynasty king, and built Western Bo, (), a new capital on the Luo River. The ruins of Western Bo are located in Luoyang Prefecture.
