Why did Qianlong do nothing or let an overseas Chinese go to ruin?

Because at that time, Qianlong thought that those overseas Chinese were all people who abandoned the Qing Dynasty and rebelled against the foreign countries, and they were so-called "people who gave up on themselves." At that time, the social environment was not to destroy overseas Chinese and Chinese, which was a kind of laissez-faire performance. His attitude towards overseas Chinese is to let them die.

At that time, there were many foreign colonies to be reclaimed, but it happened that Fujian and Guangdong in China had very large populations. Some residents can't find jobs locally and support their families, so they have to leave their homes to make a living abroad. Since ancient times, the people of China have been very hardworking. Slowly, China people who emigrated abroad became richer and richer, so more and more people immigrated from China.

With the increase of population and the gradual accumulation of wealth, overseas Chinese seriously affected the interests of the colonists to a certain extent, so the colonists promulgated some legal provisions to restrict the immigration of China people, but the effect was not satisfactory. Later, the contradiction between colonists and overseas Chinese became increasingly fierce, which eventually led to a massacre. Dutch colonists brutally killed more than 10,000 overseas Chinese and plundered countless properties. Some of those overseas Chinese were killed and burned to death. In short, the means are extremely cruel.

At that time, Qianlong in Qing Dynasty didn't help overseas Chinese. He chose to ignore the slaughter of overseas Chinese. To some extent, Gan Long thinks that the suffering of those overseas Chinese is of their own making, and they should not emigrate. Not only that, but also strengthened diplomatic relations with the Netherlands and made greater efforts to maintain friendly relations between the two countries. From now on, the practice of Qianlong is quite chilling, but people's ideas were not as open as before, so it can only be said that it was a period of people's ideas changing.
