It is 12 kilometers away from Changning station of Chengdu Guiyang high-speed railway. It is a typical Danxia gorge landform, with a forest coverage rate of 96%. There are lots of Alsophila spinulosa communities, with 47000 negative oxygen ions per cubic centimeter, ranking the first in Sichuan. The summer temperature is nearly 10 degrees lower than that of Yibin City. It is a famous scenic spot Summer resort and natural oxygen bar. There are seven cave cliff tombs (Eastern Han Dynasty), Feiquan temple, Millennium Nanmulin, 9D Yunhai glass bridge, Ganquan cave, Alsophila Valley, Hongmo Valley, Xiangbi Valley, Yanzhi Valley and other scenic spots, as well as many experience projects such as Grand Canyon Ecological drifting, high-altitude sliding rope and dry sliding road.
In February 2020, in order to pay tribute to the vast number of medical workers fighting in the front line of prevention and control, from the end of the epidemic to December 31, 2020, all medical workers in China (including Hong Kong, Macao and Taiwan) will be free of admission.
Mianxihe Grand Canyon is located at 28.5 degrees north latitude. It has a humid monsoon climate in the middle subtropical zone. With abundant rain and pleasant climate, it can adapt to the growth of various subtropical plants. The forest coverage rate of qidonggou scenic spot in the canyon is more than 96%. There is no industrial pollution. There are few indigenous residents, and the content of negative oxygen ions is very high, which makes the air here fresh. It is a rare natural oxygen bar. On April 30, 2011, the environmental monitoring center of Sichuan province carried out the determination of negative oxygen ions in yanzhituo River and yanzhituo waterfall. The monitoring results show that the content of negative oxygen ions in yanzhituo waterfall reaches 47000 per cubic centimeter. If it is monitored in summer, the negative oxygen ion content is even higher.
Qidonggou is located in the middle of a platform with an area of nearly 100 square kilometers and a width of more than 10 kilometers. The platform extends northeast to Hejiang County of Luzhou City and Jiangjin District of Chongqing, and southwest to Fulai mountain of KAIFO town of Changning County of Yibin City. The mianxi river cuts across the platform and forms the Grand Canyon of mianxi river. According to the principle of aerodynamics, the hot air rises, the cold air sinks, and the cold air on the platform continuously sinks into the Grand Canyon of mianxihe River, which makes the Grand Canyon of mianxihe River keep a low temperature and become a natural air conditioner. It is an excellent summer resort. In summer, the temperature in the scenic spot is only about 20 degrees, which is extremely cool. Outside the scenic area, there is a high temperature of more than 30 degrees and nearly 40 degrees. Every summer, farmers around, residents of Guhe Town, and even people in Changning and Jiang'an counties all meet here to enjoy the cool.
History and culture
Guhe Town, Changning County, where the seven cave cliff tombs are located, was located on the border of Cuba and Shu in ancient times. In the spring of 316 B.C., King Huiwen of Qin Dynasty sent famous counsellors Zhang Yi and doctor Sima CuO to Sichuan to lead 300000 troops to destroy Ba and Shu and unify Sichuan Basin. In order to strengthen the control of the Sichuan Basin, the state of Qin moved tens of thousands of people from Guanzhong to Bashu, diluting the Central Plains of Sichuan. In this process, the custom of tudong tombs in Guanzhong was also brought to the basin. Because the purple soil in Sichuan Basin was not as easy to excavate as the Loess in Guanzhong, the immigrants made use of the Danxia cliff in Sichuan to excavate cave tombs During the Han Dynasty, the cliff tombs in Sichuan basin developed to Dingfeng. Seven cave cliff tombs also emerged in this period. There are nearly 100 cliff tombs on both sides of mianxi river several kilometers away. During the Three Kingdoms period in the last years of the Eastern Han Dynasty, after Liu Chan, the empress of Shu, surrendered to Sima, Sima not only moved the royal family, princes and nobles, civil and military officials out of Shu, but also forced some powerful landlords and ordinary people to move about 150000 people to other places. With the exodus of powerful families, cliff cave tombs, a luxurious form of burial, are rapidly decreasing in Sichuan. During the two Jin dynasties after the Eastern Han Dynasty, there were many civil wars in Sichuan. After the establishment of the Chenghan regime, Liao people were introduced into Sichuan to enrich the towns deserted by the war. According to statistics, there were more than 100000 families and about 580000 people who came to Sichuan during the Chenghan period. At that time, the Shu area was already empty, and the Shu people were almost dead. The Liao people were fierce, and the guest was strong and the host was weak. The Shu people fled from their hometown one after another. The basin became the Liao people's world. The Liao people had the habit of living in caves. In addition, the cliff cave tomb always had the tradition of dying as if they were alive. In the tomb, there were stone stoves and stone beds in imitation of the living room of the tomb owner, so the cliff cave tomb became the ready-made residence for the Liao people.

Self service rafting by special rubber boat. The river is surrounded by beautiful scenery, green mountains and beautiful waters, and the forest covers more than 96% of the sun. The content of negative oxygen ions is very high. It is still refreshing and pleasant in hot summer. As the river goes down, sometimes it swings down in the turbulent water, sometimes it plays leisurely in the gentle water, so that tourists can feel the rare cool in summer and get psychological release.
Seven cave cliff tombs and time cable bridge
Located on the red sandstone cliff on the East Bank of mianxi River, qigedongya tombs were excavated in the Eastern Han Dynasty about 2000 years ago. In the past, the seven caves were called "Manzi caves" by local people. They were believed to be the dwellings of barbarians in ancient times. Later, archaeological experts confirmed that they were cliff tombs in the Eastern Han Dynasty. Cliff tombs are characterized by the use of cliffs to dig tombs. From the Eastern Han Dynasty to about 500 years later, cliff tombs are a typical way of burial in Sichuan, especially in the Yangtze River and its tributaries in southern Sichuan, which are very representative in the whole of China.
