Second Nanjing Bridge across the Yangtze River in Nanjing, Jiangsu (China)

The turtle and snake used to be two generals of the Dragon King, but they always fought. The King was furious and tied them at the banks of the Yangtze River. The turtle and snake transformed into two mountains. But they still  continued to fight, with the Yangtze River in between. The two mountains grew larger and larger and the waterway narrowed more and more. Upstream, the Yangtze River became blocked resulting in submerged villages and fields. When Lü Dongbin heard about this, he  came with a silver hoe. He thumped the hoe at the midsection of the Snake Mountain, and the snake’s bones were broken so the snake shrank back to the riverbank.  Lü Dongbin went across the river and built a Temple on Turtle Mountain. The huge pressure of the temple made the turtle shrink back to the riverside and could not move any more.
