Yesanpo is located in Laishui County, Hebei Province, at the intersection of the Taihang Mountains and the Yanshan Mountains. It is 100 kilometers away from the capital Beijing and 110 kilometers from Beijing, with a total area of 498.5 square kilometers. The scenic area is rich in tourism resources and is known as a "paradise on earth". (I) The natural ecology is complete and harmonious Yesanpo is known for its "wildness". The original natural environment has nurtured extremely rich animal and plant resources.

There are 184 species of wild vertebrates living with plants, including 15 species of national key protected animals, such as brown pheasants and black storks. It can be called a "natural botanical garden" and a "wildlife kingdom". (II) Typical and unique geological relics Yesanpo is located in a special tectonic position, dominating the northern end of the Zijingguan deep fault zone. Many strong tectonic movements and magmatic activities have created Yesanpo's rich content, complete types and unique geological relics. It is a vivid geology textbook and a natural geological museum. (III) Ancient Border Pass: Jade Bi Jin Tang Longmen Tianguan Scenic Area was an important pass leading from Kyoto to the outside of the pass in ancient times. It is a place of contention for military strategists of all dynasties. It is known as the "throat of the territory". It was heavily guarded in the Ming and Qing dynasties. The Dalongmen Castle, the Inner Great Wall of the Ming Dynasty and the three lines of defense constitute a strict three-dimensional defense system, which fully reflects the superb architectural art and mature military defense ideas of ancient times. At the same time, it is known as the largest historical and cultural corridor in North China with more than 30 cliff carvings praising the magnificent mountains and rivers. (IV) The green pearl shines brightly. The main peak of Baicaopan Scenic Area is 1,983 meters above sea level and is the top of the three slopes. The 100,000 mu of virgin forest is lush and green, covering the sky and blocking the sun. It enjoys the reputation of "the green pearl in Taihang Mountains". Wild animals roam in groups in the scenic area, and the natural landscape is unique. The glacier azalea, dense forest snow waves, three mountains in one view, and two forests competing for beauty are breathtaking, and the wind-moving rocks and ant ridges are daunting... (V) The brilliant revolutionary culture Yesanpo is an old revolutionary base and the central hinterland of the Pingxi (western Beijing) Anti-Japanese Base. Nie Rongzhen, Xiao Ke, Yang Chengwu and other older generation revolutionaries once led the Sanpo people to fight against the Japanese invaders together with the Eighth Route Army. Many national heroes like Sanpo's daughter Yang Huaiying emerged. The seven warriors of the Jidantuo blocking battle wrote a heroic song of Langyashan style with their blood and lives. The red song "Without the Communist Party, there would be no New China" was born here and sung all over the country. (VI) Profound and dignified historical heritage: Fossils of Homo sapiens in Laishui were unearthed here, providing a basis for studying human evolution; the Three Emperors Culture and the Hefu Culture created the splendid civilization of the Chinese nation; the legend of "Yan Wang asked for the throne, Squirrels asked for titles, and exempted from the tax" is widely circulated in the Sanpo area. To this day, the folk customs of Sanpo still retain the distinct color of the Ming Dynasty; the democratic election of "old officials" to manage all things in the slope is called "the pioneer of democratic elections and the pioneer of self-government", which is the earliest prototype of democratic elections in ancient villages in my country. The ancient and magical Yesanpo is not only a tourist destination for exploring the wild, but also a natural classroom for scientific research and study, a red traditional education base for remembering the past and cherishing the present, and an important window for Laishui's image to be displayed to the outside world.
