Introduction to Yu Palace: Yu Palace, commonly known as Yu Temple, was built in the twelfth year of Emperor Gaozu of the Han Dynasty (195 BC). According to legend, Liu Bang, the emperor of the Han Dynasty, led his army to suppress Yingbu. He passed through Tushan and visited the ruins of Dayu. In order to make future generations remember Dayu's flood control forever, he ordered the construction of a Yu temple on the top of Tushan. The Yu Palace now covers an area of more than 3,400 square meters, with five entrances facing south, and many historical sites still remain in it.
