In the sublime Xiaoliangshan Mountains of Yongming District of the Ninglang Yi Autonomous County is inlaid a shimmering pearl-Lugu Lake. It is the native place of "The Females Kingdom" ncomposed of the Mosuo people, a branch of the Naxi nationality. "Lugu" means "falling into the water" in the Mosuo language("hu" means lake in Chinese.) Hence the name of the lake.

Luguhu Lake is located between Yunnan's Ninglang contry and Sichuan's Yanyuan Country, with a total area of 77,700-odd mu, the space within the precincts of Yunnan being 41,400mu. It is 2,685m above sea level, counting from the surface of the water, and is therefore the lake with the highest altitude in the province. It's average depth of water is 40m. The greatest depth being 90m. Among Yunnan's lakes it stands only second to Fuxianhu Lake in terms of depth of water. The water of the lake is generally clean and green with different shades of color: now turquoise blue, now sapphire, now white-gray, simply beyond one's imagination, on the lake are the "Pig-trough boats" specific to the place. Teeming in the lake are fine-scaled fish, carps and other species. The lake waters flow eastwards to the Yalong River and finally into the surging Jinshajiang River.
Luguhu Lake is surrounded by high and sublime mountains and is low-bound for over 3 months. Since the lake is rather deep, a definite degulating infulence is exerted on the temperature of the lake shores. Therefore the surrounding mountains abound in forest resources which afford an exquisite beauty, much fresh air and charing scenery. At present, it is one of the places in China which is least damaged by human efforts and best preserved in its natural features.
