Introduction to Wanma Stone: "Wanma Stone" is also called "Qianyang Stone". It is made of a large pile of granite stones, like a river of stones, and is rare in the world. Legend has it that when Sun Wukong, the "Monkey King", made trouble in the Heavenly Palace, he hid the ten thousand "Pegasus" he had raised here. Later, he followed Monk Tang to go to the West to obtain scriptures and came back to become an immortal. He forgot about these Pegasus for thousands of years. After that, the Pegasus turned into stone and stayed here forever.
