It is 36 kilometers away from Kunming, and there are 326 national highways (i.e. He Kun Highway) passing through Chengjiang, Chenggong and Yiliang counties, which is named after a powerful tribe (later renamed Yang Zong) living in Dali. Ming and Qing Dynasties called Ming Lake. The lake is shaped like a huge shoe, with two wide ends and a little narrow in the middle. The altitude is 1770 meters, the length from north to south is about 12 kilometers, and the length from east to west is about 3 kilometers. The lake covers an area of 30 square kilometers, with an average water depth of 22 meters and the deepest point of 30 meters. Yangzonghai is a plateau rift lake with flat shore, uneven bottom, dense caves and reefs, green water color and high transparency. It is a freshwater lake, which is rich in famous golden thread fish. Lake water mainly comes from the surrounding Tangquan River and rainwater accumulation. 1960 due to the construction of Tang Chi thermal power plant, Baiyi River was diverted to Yangzonghai. The Tang Di Canal in Hunan is the exit. Water flows into Nanpanjiang and Pearl River systems.

Yangzonghai has beautiful mountains and rivers and pleasant scenery. Longquan Temple in the southeast of the lake is surrounded by stone walls, overlooking the lake ahead, and a spring water gushes out from the mountainside, clear and clean. There are 1 ancient trees near the temple, with a diameter of about 2 meters, which are more than a thousand years old and flourishing. Xiaotun village in the south is said to be the place where General Ge Liang stationed Guan Suo during the Three Kingdoms period. The villagers still sing the ancient Nuo opera, commonly known as "Guan Suo Opera". There are seven huge stones in the back of Guobao Temple in the southwest of the village, which are naturally arranged in the shape of the Big Dipper, and are called the "Seven Stars and Big Dipper". The nearby village is called "Beidou Village". Every summer and autumn, when overlooking Yang Zong Bazi, you can clearly see every village. Only Beidou Village was shrouded in smoke cages and fog. The ancients called this wonderful scene "the misty rain in the village" with unique scenery. In Tangchi Town, northeast of the lake, a provincial-level tourist resort has been built, with seaside amusement parks, golf courses, Xiaobailong Forest Park, Jinyong Resort, Tang Chi Hot Springs and other tourist and entertainment service facilities. Shicun Yanyu, also known as Doucun Yanyu, is located in Beidou Village in the middle of Yang Zong Bazi.

Beidou village used to be on a raised hill. There is a "national security temple" in the village. There are seven natural stones behind the temple, which look like the "Big Dipper" in the sky, hence the name "Beidou Village". The historical records are "misty rain in ten villages", but the people call it "misty rain in Doucun". It seems that it is more accurate to call it "misty rain in Doucun" than "misty rain in Ten Villages". Autumn wind in Songling, also known as "autumn wind in Songling", is called "thunder and stone" by the local people in the middle of East Mountain of General Manager Yang.

The mountains in Dongshan area are formed by the ups and downs of fault rocks. Some rocks have become loose due to weathering. Due to wind, rain and thunder, rocks fall off and roll down. Some people think it is lightning, so they call it "Leishi". Nantan Gaoze is located in Xiaotun Village at the foot of Wang Liang Mountain. It is said that Zhuge Liang and Guan Suo camped here. They found that the Longtan water in the south of the village emits seven colors of light, namely red, orange, yellow, green, cyan, blue and purple, hence the name. Nantan is the water dragon pool in Xiaotun village, which provides drinking water for people and animals in the village. The bottom of the pool is flat, with fine white sand, and water emerges from red crevices. There are many dragon trees beside the pool. At noon, the sun falls from the leaves, forming a seven-color reflection and shaking wonder. Nantan is also a sacrificial place for ancient Guansuo drama. Xiaotun Guansuo Opera is the spread of Nuo culture in China. "Nuo sacrifice" refers to wearing a mask to ward off evil spirits during sacrifice. Before the performance of Guan Suo Opera, all the actors knelt down at Lingfeng to worship the "King of Medicine" (Guan Suo), asking him to descend from the sky and use him to suppress evil spirits. After the performance, there will still be a ceremony to worship the great god Guan Suo, and the memorial tablet of Guan Suo will be taken down and burned next to the south altar, so that the great god Guan Suo can return to heaven.
