Mountain Lutang, with a height of 385m, is the place where Lu Wang Village and Jiuzigou lie. The mountain, surrounded by water on one side and cliffs the other three, has only one access to the village. Legend has it that during Shang Dynasty, Chi You, a valiant general of Emperor Zhou of Shang Dynasty, followed his emperor to fight battles. Afterwards Emperor Zhou imposed a cruel rule on the innocent people. Chi You gave up his service to the emperor and came down south towards the banks of Zhentou River of Huaihe River Reaches. He found the place abundant with natural resources and sceneries and stationed there. When Emperor Wu knew that Chi You rose against Emperor Zhou, he sent an envoy to discuss over joining forces and overthrowing Shang Dynasty.
Chi You agreed and submitted to the rule of Zhou Dynasty ever since. Emperor Zhou conferred Chi You the title of “Prince of Lu”. Knowing Chi You's betrayal, Emperor Zhou was furious and led the army to attack Lu Wang Village. It was a fierce battle. Nine sons of Prince Lu died on the way to the village, that is why the place is named Jiuzigou (literally, a valley of nine sons). Now there are still ruins for people to recall the past, such as the ancient battle field, training yards, and valley where the army was stationed.
