Introduction to Crocodile Valley: Crocodile Valley is an east-west ravine 1 mile north of Momo Stone. There are steep mountains and jagged rocks on both sides of the channel. Legend has it that in ancient times, a crocodile with many evil deeds occupied this ditch, doing evil and causing harm to the people. In order to relieve the plight of the people, Lu Dongbin started a battle with the crocodile here. After the crocodile was defeated, it turned into a ravine.
