Introduction to Kuaishan Mountain: "Jieya Mountain", one of the famous mountains with far-reaching views, is called "Quaiya Mountain" by the locals. The peaks of this mountain are concave at both ends, like a missing tooth in a row of neat teeth. The mountain is more than 800 meters high and is the second highest peak in Dongyuan County. It is said that this mountain can "forecast the weather". In spring and summer, if the fog on the top of the mountain disperses, it means it is sunny weather, otherwise it will be rainy. The nearby villagers used to rely on this experience to arrange farming.
