Why did the Qing dynasty close its doors?

In fact, since the Anshi Rebellion, China has been closed to the outside world. It was only in the Qing dynasty that the closed door reached its peak.

Let's talk about the Anshi rebellion first. As we all know, the way of communication between the Tang Dynasty and the outside world, including the past dynasties, was the Silk Road, and there were also water exchanges, but it was not as convenient as the Silk Road. So the Silk Road supported many countries and many people. However, after the Anshi Rebellion, due to the shift of the capital and economic center of gravity, the Silk Road began to be abandoned gradually.

Until the Ming Dynasty, the Silk Road almost disappeared in the slow yellow sand, just like the ancient country of Loulan. Especially after Zheng He's voyage to the West, the Ming Dynasty began to implement the maritime ban. Ordinary people are not allowed to go to sea at will. At this time, the land and water were blocked and the country was closed.

In the Qing dynasty, in order to better control people's minds, the closed door reached its peak. It is for this reason that the Qing dynasty began to stagnate, and even the ministers who made "machine guns" were exiled. The Qing dynasty always felt that its red cannons and cavalry were leading the world.

Therefore, this fat meat of the Qing Dynasty, this frog in the well, was finally opened to the world by the artillery fire of the great powers. It became a semi-colonial and semi-feudal society. Finally, it was completely extinct.

To sum up, the Qing dynasty only closed its doors on the basis of the previous dynasty. It can't be said that the Qing dynasty began to close its doors. The Qing dynasty only carried forward this bad policy. The Qing dynasty needed a back pot, but it could not be put in the whole pot. Speaking of backbiting, I think everyone needs backbiting since the Anshi Rebellion, don't they?
