Nowadays, the refugee problem has become a problem in the world, and the root cause of this problem is that the war launched by Western countries has led to countless people being displaced, these refugees have been forced to leave their homes in search of a glimmer of life, although the suffering of these refugees is sympathetic, but our country has never been willing to take in refugees, but European and American countries like to take in, and often accuse our country of being too cold and cruel.
In fact, the refugee problem is originally created by European and American countries, so who makes who solves it, and the reason why European and American countries are willing to take in refugees is not because they are kind, but because they want to obtain a large number of cheap labor, and the reason why our country is so cautious about the refugee problem is because we have had a particularly heavy lesson before, and every time we take in refugees, it will bring us a huge disaster.
In the Han Dynasty, the Central Plains regime has been harassed and threatened by the Xiongnu, and then there was infighting within the Xiongnu, the Southern Xiongnu defected to the Eastern Han Dynasty, they joined forces to drive the Northern Xiongnu away, but the Southern Xiongnu began to rebel after entering the countryside in the Central Plains, and in the Western Jin Dynasty, it subverted the Han regime in the Central Plains, bringing deep suffering to the people, in addition to the Tang Dynasty and the Ming Dynasty, China was plagued by taking in refugees.
The Anshi Rebellion was a turning point in the Tang Dynasty's transition from prosperity to decline, and the culprit of all this was the Tang Dynasty's refugee An Lushan and millions of Eastern Turks, and the Ming Dynasty was also because the imperial court tolerated Nurhaci's occupation of the Liaodong region and let it go unchecked, which eventually led to a catastrophe.
