Embracing 250 square kilometers, Erhai Lake lies at the eastern foot of the Cangshan Mountains and is a famous fresh-water lake, 40 kilometers long from north to south, 7 to 8 kilometers wide from east to west, lying on a plateau of 1,980 meters above sea level. The crescent-shaped lake contains crystal cool water. In praise of the beautiful scenery, people often say “Ten thousand acres of water reflect the sky like a mirror and the surrounding mountains stand there like an evergreen screen in all the four seasons.” The lake teems with fish, such as mackerel, silver crap, crucian carp, stingrays, variegated carps and others. The lake shapes like an ear, and waves are big enough in the lake, hence the name.
