The Mosuo people who live around Lugu Lake in Yanyuan County, Liangshan Prefecture, Sichuan Province and in Lijiazui Group, Wujiao Village, Wujiao Township, Muli County, are all Mongolian. This ethnic group worships nature and ancestors very much, believes in "Dabaism" and "1 Religion", and advocates nature worship and polytheism. Because people have a close relationship with nature in their long-term production and life, the Mosuo people are full of worship for various gods, sacred mountains, and Haizi (locally known as plateau lakes) in their material and spiritual lives. The Lake Turning Festival is the embodiment of the primitive beliefs of the Mosuo people. [Era of Origin] The Mosuo people call themselves "Na" or "Nari", and historical records call them "Mosuo" or "Mosuo", "Moxi", "Mosha" and other homophones. The Mosuo people believe in Dabaism. After Tibetan Buddhism was introduced to the local area in the late Yuan Dynasty and early Ming Dynasty, they believed in 1 Religion on the basis of their belief in Dabaism. Dabaism believes that all things have spirits, worships nature, worships stone ancestors, worships ghosts and gods, worships goddesses, female ancestors and women, and is a typical primitive religion. The Lake Turning Festival, which the Mosuo people have preserved to this day, is one of their ways of worshipping nature, worshipping multiple gods, and offering sacrifices to the lake god, water god, goddess, and female ancestors. Regarding the origin of the Lake Turning Festival, the Mosuo people in Muli said that it was brought by Mongolian nobles from the north. The Mosuo people around Lugu Lake in Yanyuan have two legends: one is that the area around Lugu Lake was originally a depression, which was formed because a big fish blocked the spring mouth1. Only a woman who was feeding pigs bravely and cleverly jumped into the pig trough boat and survived. This woman became the ancestor of the reproduction; the other is that a pair of male and female fairy lovers living in the east and west of the lake were separated by the gods, and the goddess' tears merged into Lugu Lake. Circling the mountains and lakes is to worship female ancestors and goddesses. [Distribution Area] The Lake Turning Festival is distributed in Lugu Lake and its surrounding areas at the junction of Sichuan and Yunnan, including the Mosuo villages of Mukua, Duoshe, Boshu, Shekua in Lugu Lake Town in Sichuan and the surrounding Qiansuo, Wujiao, Changbai, Gaizu and other townships, and dozens of Mosuo natural villages such as Yongning and Labo in Yunnan. Muli County is mainly distributed in Wujiao Township, Xiangjiao Township and other villages where Mongolian and Mosuo people live. [Basic Content] The first, fifth, fifteenth and twenty-fifth day of each lunar month, and Muli is the eighth day of the first lunar month every year, is the festival for the local Mosuo people to turn the lake. It is said that the gods come out on these days, so the Mosuo people welcome the gods with grand sacrifices and festivals, worship and sacrifice, in order to seek blessings, and have fun with the gods. People from all villages and households go out of their homes and form a large team to carry out the Lake Turning Festival. In Muli County, wealthy families also invite "Daba" to accompany them. Men, women, old and young who participated in the event wore festive costumes, brought chickens, eggs, meat, Surima wine and other rich foods, helped the elderly and children, and walked, rode horses, or took boats around the mountains and lakes. At certain places along the way, there were incense burning and sacrificial points. They stopped to chant scriptures, burn incense, kowtow and pray for blessings to the lake god, the goddess Gemu in the west of the lake and the surrounding mountain gods, blow conch shells, beat gongs, drums and ring bells, and perform grand sacrificial ceremonies. They also threw "Rilubu", which is bitter buckwheat popcorn for worshiping gods, symbolizing the white sheep, blue sheep and harvest of worshiping gods, among the mountains and rivers. The lake circumambulation starts in the early morning and completes a circle around Lugu Lake and its sea of grass until the evening. People entertain and worship at the same time. Along the way, the red and green lake circumambulation team is like a colorful long dragon, swimming between the mountains and rivers. Wisps of green smoke from burning incense are rising in the mountains, and pig trough boats with green smoke are also accompanying them in the lake. The circumambulators on the boats in the lake echo the men and women on the lakeshore. When they reach the place where they have a picnic, they hold a grand Jiacuo dance, folk songs and love songs, horse racing and wrestling, etc. The joyful singing, flute and laughter echo in the valley for a long time. In Muli, there is a fixed route for "circumambulating the mountains and lakes". Pray according to the customs of each family. The route is generally clockwise and on foot. Every family has countless fixed incense piles along the way, and they first burn incense and chant scriptures at each place. The various spices, grains, milk and objects blessed by the local temple are placed on or around the Mani pile. At the same time, all the auspicious words and chanting words are recited together, and each person prays and wishes for family happiness, healthy growth of children, prosperity of livestock and good harvest of grains. There are three types of circumambulating the mountains and lakes: big circumambulation, medium circumambulation and small circumambulation. The big circumambulation takes about 15 days, the medium circumambulation takes about 9 days, and the small circumambulation takes about 7 days. 【Basic Characteristics】1.
