First of all, it is the predecessor of the Qing Dynasty, so after the establishment of Nurhachi, it has the right to manage. This is Nurhachi's base. At that time, Manchu people regarded Changbai Mountain as the birthplace of Manchu and the sacred mountain of culture. In fact, Nurhachi banned idle people from staying in Changbai Mountain at the end of Jin Dynasty. Nurhachi occupied the Northeast for a long time, gradually developed and finally dominated the Central Plains.
However, after the establishment of the Qing Dynasty, Changbai Mountain was occupied and regarded as the land of Manchuria. From the perspective of geomantic omen, the shape of this mountain is similar to that of a dragon. Changbai Mountain is the largest underground Long Mai in the world and is called the Dragon. Emperors of all ages wanted to protect their Long Mai. For example, Qin Shihuang cut off Long Mai in Nanking. In order to prevent the Han people from destroying the Long Mai of Changbai Mountain, the Qing Dynasty banned the exploitation of resources in the northeast of Changbai Mountain, which was rich enough to become the capital of Manchuria. Once the southern rebels attacked the north, the Qing government could return to the northeast base camp. However, with the increase in the number of people passing through Kanto in Shandong and Hebei, Emperor Xianfeng was forced to lift the ban. Later, a large number of Han Chinese flooded into the northeast, and the idea of building the capital in the Qing Dynasty became a fantasy.
First of all, we know that the Qing dynasty not only blocked Changbai Mountain, but even blocked most parts of Northeast China. At that time, in order to prevent Han people from colluding with foreigners, the northeast was banned, and the northeast was rich in natural resources and animal and plant resources. In order to build the northeast into a treasure house of the royal family, the Qing royal family banned Han people from going to the northeast.
However, the prohibition of grazing in Northeast China in Qing Dynasty was also beneficial to protect the animal and plant resources of Changbai Mountain. In order to prevent Han people from assimilating Manchus in Northeast China, the Qing Dynasty banned Han people from entering Northeast China and Changbai Mountain.
