Introduction to the Sea of ​​Clouds: Ruili was originally a simple mountain village. Because it is located in the frequent cloud and fog zone, the clouds and mist are misty all year round, and the sea of ​​clouds landscape is magnificent. Changshan Sun View Peak is located on the ridgeline. It is a good place to overlook the lights of Alishan, the white snow of Yushan or the sea of ​​clouds in the Wufeng Township Valley.
