Who knows what happened to Niangniang Mountain in Laiyang City?

Legend has it that Niangniangshan used to be a nun. One day, an old nun sent a little nun down the mountain to fetch water, and the little nun never came back after going down the mountain. Many young nuns left one after another, all making the same mistake. Finally, the old nun was thirsty, so she went down the mountain to see a huge old turtle lying at the entrance of the mountain with bright red blood in her mouth. The old nun returned to the mountain. Later, when the old nun saw that the old turtle didn't leave, there was no water.
