Introduction to Puyang Lake: A blue lake, silent in the forest without any ripples. Time seems to have stopped here, and the years have quietly left no trace. That blue has immersed itself in countless mountain colors, intoxicated by the spring breeze, and the grass carp pond has quietly retained the blue sky. After blending it with water-like tenderness for many years, it finally condensed the dark green hidden in a lake into a blue sky. Deep eyes. The pure sky, not a trace of noise, not a particle of dust, everything in the world seems to be isolated in another world.
