The northern mountain of Daxian, today's Daxing 'anling, is the birthplace of Tuoba family in the Northern Wei Dynasty. According to the data, the Xibo nationality in China, that is, Xianbei Mountain in history, is quite famous and aura among the peaks in Daxinganling. Between the cliffs, Gaxian Cave appeared in front of us. This cave is high, wide and deep, and it is the stone chamber of the old market where Xianbei ancestors lived. It is over 1550 years ago. Fireworks in ancient times enriched nature and made mountains and rivers truly magnificent, evergreen and perfect; And the mountains create a living environment for human beings, so that the life that melts into the mountains will always be tenacious, fresh and sustainable. The Oroqen people who live here have long understood this truth. They worship nature and believe in animism. In their eyes, the mountains are full of mountain gods, river gods, tree gods, flower gods, bird gods, Shen Feng gods and Raytheon ... so they try their best to protect the precious wealth of nature. There are no hacked knives and saws here, no fires here, no poaching here, and everything here is like the original state. With the development of tourism, everyone thinks that an asphalt road should be built in the mountains, but they resolutely give up because they are worried about destroying the ecology. The Oroqen people's awareness of environmental protection is so bright and strong. The Great Xianbei Mountain is still the Great Xianbei Mountain in ancient times. Towering trees that have experienced a lot of rain and snow, or collectively stand on hillsides and valleys, or stand proudly beside rocks alone, swaying clouds, old and green, forming their own landscape. The birch and purple oak trees here are beautiful and unique. No matter what their growing environment is, they have to take deep roots, and the branches and leaves that change color from time to time always stretch desperately and decorate the mountains. In Shan Ye, dense forests, all kinds of birds flock together, or grass condenses, or sings, or dances in the air, which is cheerful and free. Due to the dense trees, there are more than 50 species of wild animals such as moose, red deer, black bear and roe deer in the forest/kloc-0, and more than 30 species of national first-class and second-class protected wild animals. Perhaps it is because of the existence of these wild animals that the northern mountain of Daxian is so quaint and spectacular. From time to time, I encounter heavy rain on the mountain, which is as fierce as thunder and makes people unable to escape. After a while, the rain suddenly stopped, the sun shone brightly, the sky was as clean as washed, the trees were green, and the rocks seemed wet and soft. Friends of the Oroqen people tell us that this is a primitive natural phenomenon, which is related to ecology. The mountains are quiet and noisy. There is a Gaxian River at the foot of the mountain, which flows around the mountain. I have never seen such a river. The blue sea is crystal clear, the fine spray is crystal clear and pure, and the fish swim around happily and freely. The river is so cold and sweet that people can't help drinking a few mouthfuls. According to the rules, after washing our eyes and wiping our faces with river water, we observed a moment of silence. The Shenhe River mentioned by the Oroqen people is this river.
