Why did the Ming dynasty's maritime ban become waste paper and the Qing dynasty succeeded?

During the reign of Kangxi, the Qing emperor decided to move to the sea in order to isolate Taiwan Province Province from the mainland. How does the process of coastal movement proceed? Is it like the Three Gorges immigrants now, first resettle the immigrants and give them appropriate economic compensation, and then move the residents out step by step? Don't! The process of coastal migration is not so much immigration as unprecedented slaughter and plunder.

According to the records of the people at that time, "the detention period is only three days, and those who are far away don't know, and those who are near don't believe it." After more than two days, I rode there one by one. For a while, the rich abandoned it, while the poor looked after the kettle, his wife and children, carrying a bucket of rice and a pile of manuscripts, and looked at the door. From Jiangsu and Zhejiang to Fujian and Guangdong, thousands of miles of fertile soil were donated as wormwood, and the indigenous people were moved. "

Translated into vernacular, it means moving within three days. People far away have no time to know the news, and people near will not believe it even if they know the news. Two days later, the army cavalry arrived, so the rich people abandoned their wealth, and the poor people took their wives and children with pots and were all displaced. From Jiangsu and Zhejiang to Fujian and Guangdong, thousands of miles of fertile soil along the coast have all turned into wild Artemisia.

It is conceivable that even if modern people intend to implement it, the specific operation preparation will certainly not be completed in three days. But at that time, the coastal residents of China were forced to leave their homeland without any warning, and their tragic situation was unknown.

At that time, people described it as "that day, my wife walked away, took her bedroom and set fire to it, leaving no rubble." When a man is half dead, he draws a picture on his pillow. It is the first or second person who can reach the mainland. Stone has no food and is starving at present. ……"

In other words, when they moved, more than half of the coastal residents died, and less than 20% of the people left, even if they could go to the mainland, were not far from starvation.
