Quotes about gurgling (2 Quotes)
Snow The scene is the north lands. Thousands of li sealed in ice, en thousand li in blowing snow. From the Long Wall I gaze inside and beyond and see only vast tundra. Up and down the Yellow River the gurgling water is frozen. Mountains dance like silver snakes, hills gallop like wax bright elephants trying to climb over the sky. On days of sunlight the planet teases us in her white dress and rouge.
