Introduction to the sea of clouds: When the fog comes, the peaks are alive, and when the rain comes, the pines and waves rush. Wisps of green smoke, winding around the pointed peaks, move gracefully, like mist moving away, like peaks moving. Especially when it clears up after the rain, the sea of silvery clouds rises and falls under your feet, with different shapes. Where the clouds and mist are thin, you can occasionally see the peaks of green peaks, and the pines look like paintings, making you feel like you are in a fairyland.
