Why did the Qing dynasty ban Changbai Mountain for 2 16 years in history, and then why did it lift the ban?

Because this is the base camp of the Qing dynasty, I don't want to be destroyed by outsiders. Later, it was unsealed because there was a natural disaster in Shanhaiguan, and people at that time had nowhere to go and could not unseal it.

We all know that the predecessor of the Qing Dynasty was Jin, and Jin was established in this place in Northeast China. They have great affection for this place. This is their home, and there are many rich resources they created before. They don't want to be destroyed by others.

Another problem is the geomantic omen of Changbai Mountain. Changbai Mountain is shaped like a dragon. In the past, people thought this was Long Mai, which was closely linked to the fate of their own families. You can't destroy it, you should protect it.

At that time, in order to better protect this Long Mai, Shunzhi surrounded the mountain with railings, so as not to let anyone in, for fear of cutting off his Long Mai.

Another reason why this place had to be closed was that it was the second reserve capital of the Qing Dynasty. If one day you can't stay in the Central Plains, you can go back to this place in the northeast to continue to raise troops. Because this place is rich in resources and has a good geographical position, it can protect its own strength from being weakened.

The reason why it has been banned for so many years is that every king knows the development history of his ancestors very well, and he also knows that this is to have more choices in the future.

However, during the Xianfeng period, a serious natural disaster occurred in Shanhaiguan, and later the chaos in the imperial court caused many residents to have nowhere to go, not enough to eat and not enough to wear. Finally, under the pressure of public opinion, Xianfeng revoked the ban on Changbai Mountain.
