During the Qianlong period of the Qing Dynasty, Russia began to slowly enter Sakhalin Island. Does the king really not know?

Sakhalin Island has been an inalienable part of China's inherent territory since ancient times. First, in the history of geographical discovery, China was the first country to know about Sakhalin Island. Second, China was also the first country to administer Sakhalin Island. Since the Tang Dynasty at the latest, China has been under the jurisdiction of the lower reaches of Heilongjiang and Wusuli rivers, including Sakhalin Island.

Sakhalin Island is the border area of our country, and the Qing government thought it was barren, so it didn't pay special attention to it. The Qing Dynasty did not set up an army in sakhalin island, but only stipulated that three generals, namely, Fengtian, Jilin and Heilongjiang, would make a patrol every five years. So all the information about Sakhalin Island was learned from officials, but the fact was not clear to Emperor Qianlong at that time. In fact, the army of the Qing government did not patrol Sakhalin Island on time, but perfunctory the emperor. They thought that the sky was high and the emperor was far away, and no one said anything.

Later, Russia began to get its hands on Sakhalin Island. Russian invaders slaughtered Hezhe residents on the island, deported them back to the mainland, and built halls, churches, prisons, schools and other buildings in the mother-child berth, completely occupying sakhalin island. This year was the Qianlong period of the Qing Dynasty. 1789 Gan Long is 78 years old, his thinking and ambition are not as good as when he was young, and the country is not peaceful. There are wars in Taiwan Province Province and Tibet, basically in the south, but for Sakhalin Island in the north, Gan Long has no time to take care of it, because from the original intention, he doesn't want wars on both the north and south lines. Therefore, in response to the Sakhalin massacre, Qianlong was nothing more than diplomatic rhetoric, strong condemnation and so on.

Now, we know that Sakhalin Island is by no means barren, but a region rich in resources. Oil reserves are 2 billion tons, natural gas is 700 billion cubic meters, iron ore is 4.4 billion tons, and there are countless mineral resources such as copper, tin, manganese, diamonds and coal. If the Qing government knows, it will definitely be angry.
