Is that really the case? How to comprehensively evaluate Emperor Kangxi himself? This is really a difficult problem. But one thing seems to have to be said, that is, Emperor Kangxi didn't seem so "wise" when he forced the demolition. It all started in March of 166 1, and Zheng successfully landed in Taiwan Province province, and he was invincible all the way. The Qing government was furious and issued a cruel "immigration order". This was cruel, but in 1662, the Dutch governor who occupied Taiwan Province Province signed the surrender, and Zheng Chenggong completely recovered Taiwan Province Province. When the news came, the Qing court was livid and issued an "immigration order" again.
According to the border relocation order, residents of 24 counties in Guangdong Province, including Raoping, Chenghai, Jieyang, Chaoyang and Huilai, will be forced to move another 50 miles. Except Macao, all nearby islands and ports will be closed, destroyed and banned from living. The imperial edict also stipulates that all houses in the restricted area shall be demolished, fields shall not be cultivated, fishermen shall not go fishing in the sea, and those who leave the boundary shall not be pardoned. What was the result? It is roughly estimated that the death toll in eight counties in eastern Guangdong alone reaches hundreds of thousands. Qu Dajun wrote sadly during the years of Yuedong New Language: "Since Yuedong, the disaster of life has never been so deep." Unfortunately, this is very powerful, and Emperor Kangxi didn't do it thoroughly enough. So in May of 1664, the court also called it "the people moved fish and salt, fearing to cross the sea again" and ordered them to move within 30 miles again. Residents in Shunde, Panyu, Nanhai and Haiyang, which are not within the scope of demolition, staged another round of demolition tragedy.
As for the consequences of prohibiting going to sea and moving the border, historians have analyzed that this is a self-restraint approach. Why? This means that the Qing court entered the snail shell, but the world has undergone earth-shaking changes. Emperor Kangxi's practice is not only far from the ocean, but also far from reality. Some historians even think that Kangxi carried out the "Migration Order" with a narrow nomadic consciousness, which made China fall behind the world. Finally, during the Qianlong period, western countries began to successfully meet modern civilization. We have seen the final result and painful experience, and we certainly don't want it to happen again.
