All Tibet lake have their own legends.
Lhanag-tso Lake is also called Ghost Lake, which means “poisonous dark lake” in Tibetan languages. Lhanag-tso Lake is located next to the holy Manasarovar. The legend goes that there is a cosmic door under the lake which connects the two lakes together. The water qualities of the two lakes are totally different. The water in the holy lake - Manasarovar is sweet and fresh, while the water in the ghost lake tastes bitter and bad. The ghost lake and the holy lake live under the same snow-capped mountain. There is no hatred or war, only the bleak years that have been together for hundreds of millions of years. The ghost lake often has three-foot waves without wind, and the lake is surrounded by dark red hills with weird and blurred colors.
