From Zha Dapu, you need to return to the Balbest Station first, then continue eastbound along G219, then transfer to the 207 Provincial Highway, passing through the holy lake Malang and the ghost lake Laon. Langang, known as Ghost Lake, Tibetan means "poisonous black lake", located in Pulan County, Ali, at an altitude of 4,574 meters, separated from the holy lake of fresh water, is a brackish water lake, so its lakes and animals are Can not drink, so there is a "ghost lake." Ghost Lake Laangso is a close neighbor of the holy lake. The scenery is equally beautiful. The lake is also blue and fascinating, but it is deceptively labeled as Ghost Lake. In fact, the holy lake of Ghost Lake was originally a lake. Later, the debris contained in the glaciers accumulated in the middle of the original Great Lake after the glaciers melted, causing the lake bed to rise. After that, global warming, evaporation increased the glacial shrinkage, the amount of recharge water decreased, and the lake area shrank. The lake's water level dropped, and finally it was divided into the current holy lake and ghost lake. Take the Ghost Lake for three consecutive days. The scenery of the Ghost Lake is different in different weather. The lake is dark blue when the weather is fine. When you are lucky, you can see the Mount Kinabalu. Walk the lake, the cold wind rushes to the surface, and the sound of the waves is touching.
