Shuigou Qin-Han (Hui Zhong Palace) Ruins

　　The Shuigou Qin-Han (Hui Zhong Palace) Ruins are situated about 1 kilometer north of the county town, on the western side of Shuigou Village in Xiangshui Town, covering an area of around 300,000 square meters. It has been confirmed as a Qin-Han period site. Some historians also believe it to be the site of the Qin-Han "Hui Zhong Palace." The surface of the ruins is scattered with numerous rope-patterned roof tiles, tubular tiles, and cloud-patterned tile ends. Artifacts excavated include gray pottery jars, iron lamps, iron cauldrons, as well as bronze coins such as "Ban Liang" and "Wu Zhu." Remnants of bronze crossbow mechanisms and underground clay drainage pipes—architectural materials from the Qin-Han era—have also been unearthed. According to Records of the Grand Historian: Annals of Qin, in 220 BCE, Emperor Qin Shi Huang toured Longxi and Beidi commanderies, passed by Chicken Head Mountain, and stayed at Hui Zhong Palace. Chicken Head Mountain is located within Jingyuan County, where Emperor Qin Shi Huang once camped during his border inspection tour. In 166 BCE, 140,000 Xiongnu cavalry raided the Central Plains and engaged in a fierce battle with Sun Ang, the Commandery Defender of Beidi under the Western Han Dynasty, at Xiaoguan (in the vicinity of today’s Sanguankou). Sun Ang bravely faced the enemy and died in battle. As they withdrew, the Xiongnu burned down Hui Zhong Palace, and traces of the fire can still be seen at the site today.
