Village introduction: Xinguangwu Ancient City, also known as Xinguangwu Village, is one of the most complete ancient cities in Shanxi Province. It was built on the Chengguan site of the Warring States Period in the seventh year of Hongwu in the Ming Dynasty (AD 1374) and rebuilt in the third year of Wanli in the Ming Dynasty (AD 1575). This place is surrounded by dangerous mountains and stands in front of Yanmen Pass. The Han Dynasty set up counties and counties here and stationed troops to guard it, which effectively played a role in resisting the Xiongnu's southern invasion. In the Ming Dynasty, many military castles were built along the Ming Great Wall to resist the Mongols, and Xinguangwu City was one of them. This kind of castle houses crops in peacetime and goes out in wartime. In peacetime, it also has the economic functions of trading market and selling market. But its military function has always been primary.
