Yang Sheng 'an, a famous scholar in the Ming Dynasty, described it as "the mountains and Qinghai are blue and half moon" and "looking up at the sky without feeling refreshed, flying over the eaves and climbing over the walls". At the foot of Cangshan Mountain and the shore of Erhai Lake, there is also a famous tourist attraction-butterfly spring. Butterfly spring's fame is related to Xu Xiake's description in his travel notes. He wrote: "There are big trees on the spring. In early April, flowers will be like butterflies, and their wings will be like butterflies. There are also tens of millions of real butterflies, all hooked on their feet, hanging upside down from trees and reaching out to the spring, which are colorful. " It is true that there are countless butterflies coming to this party, and their colors are gorgeous, such as summer. The number of butterflies decreased a few years ago. According to the investigation of relevant parties, the main reason is that the local climate turned to dryness, which led to butterfly migration, and a large number of pesticides were used in rural areas, which accidentally injured many butterfly larvae. However, in recent two or three years, with the gradual restoration of ecological balance and people's conscious protection measures for butterflies, the number of butterflies gathering every year is increasing day by day. -The tourist scenic spot of Dali Foreigners Street in Yunnan is in the ancient city. Dali Foreigners Street was originally called "Protecting the Country Road", which means that in the early years of the Republic of China, the people of Yunnan opposed Yuan Shikai's claim to be the emperor and rose up to protect the country. Huguo Road runs east-west, with a length of 1 000m and a width of 7m. Paved with bluestone slabs, it starts from Yunnan-Tibet Highway in the west and crosses major streets such as Bo 'ai and Fuxing. Later, in order to meet the needs of open tourism, Dali ancient city was designated as the main attraction of open tourism, and Camellia Hotel was designated as a foreign-related hotel. Camellia Hotel is located in the west section of Huguo Road in the ancient city, so Huguo Road has become a distribution center for foreign tourists in Dali. Chinese and western flavor shops, jewelry stores, antique shops, tie-dye shops and galleries have sprung up like mushrooms after rain, and the pavements are lined up on both sides, making them a famous "Dali foreigner street" at home and abroad. Today, the name of the ancient city of Dali, Huguo Road, has long been called "Foreigner Street" on some foreign drawings. It can be seen that Dali foreigner street has become a world-famous place for foreign friends and a warm home for them to live in Dali. -Three Pagodas of Chongsheng Temple in Dali, Yunnan The three pagodas of Chongsheng Temple are symbols of the ancient history and culture of Dali and Yunnan, and they are also one of the oldest and most magnificent buildings in southern China. -Dali (now Dali City), the ancient tourist scenic spot in Dali, Yunnan, is referred to as Yucheng for short.

It is located in the east of Nanzhao, the ruins of Dali capital. It was built in Hongwu 15 year of Ming Dynasty (A.D. 1382) and has been used repeatedly in past dynasties.

The garden teahouse hidden deep in the streets is a good place for tourists to rest.

Due to long-term landscape erosion, sand and gravel are in pieces, and trees are scarce on the hillside. But when you walk slowly uphill for about half a mile, you will see a dazzling shadow. Walking through the quaint stone square, there is a marble tablet about 3 meters high, which is prismatic, and on the right side there are three characters of "butterfly spring" written by Guo Moruo. On the left is the handwriting of Lao Guo's poem butterfly spring. On the back of the tablet is a diary of Xu Xiake's visit to Dali butterfly spring. Winding along the tree-lined path for about 30-40 meters, I saw many ancient trees, a clear spring embedded in them, bluestone at the bottom, and spring water in Ming Che. People often throw metal coins into the pool and watch it spin slowly. The sun was blocked from the top of the tree, and the silver light at the bottom of the pool flashed, which made me feel the spring water clear. There is a marble wall around the spring pool, and a tall old tree spans the spring. This tree is called "butterfly tree" because its flowers look like butterflies. Whenever summer comes, the "butterfly tree" blooms, and the butterflies of Xanthium come here in droves, gathering and dancing, which is very lively. The strangest thing is that thousands of colorful butterflies cross each other in spring and hang upside down on butterfly trees, forming countless strings of butterflies hanging vertically to the water, which are colorful and spectacular. The peak period is around April 15 of the lunar calendar, so April 15 of the lunar calendar is designated as the "Butterfly Festival". -Xizhou, a tourist scenic spot of Bai folk houses in Dali, Yunnan, is located at 16 km north of Dali ancient city.
