What if China now had the territory of the Qing Dynasty?

It is said that history cannot be assumed, and what happened happened. But let's assume that it's interesting to open your brain wide.

If China is still the territory of the heyday of the Qing Dynasty, China is at least 3.5 million square kilometers more than it is now, which is equivalent to 27 English, 1 Japanese and 7 French!

then, as a native of Jilin, I will be overjoyed! Why? Jilin's administrative areas in the Qing Dynasty include the eastern part of Heilongjiang, the vast area east of Wusuli River and Sakhalin Island (equivalent to nearly three Taiwan Province), with a coastline of several thousand kilometers and an area of over 1 million square kilometers, which is definitely the largest coastal province in China. Moreover, the mineral resources are extremely rich. The oil reserves and output of Sakhalin Island are no less than that of Daqing, and there are almost unlimited forest resources, and the scenery is extremely beautiful. According to the present conditions of our country, this large territory will be developed reasonably, scientifically and effectively. In terms of tourism, Jilin Province will definitely not lose the two rivers, Guangdong, Guangxi and Fujian. After the holiday, we can also go to Sakhalin Island for recreation and enjoy ourselves on the coastline stretching for thousands of miles at the foot of Sihot Mountain. Militarily, Jilin can become an important military base in China, and one of the largest Pacific fleets in the world can be stationed on Sakhalin Island, dominating the western Pacific, containing Japan, resisting the Russian Far East and approaching Alaska in the old United States.

Let's talk about other areas. The north has the whole of Mongolia (including Tangnu Wulianghai area), and the west has several great lakes, all of which kill Qinghai Lake. The southeast owns the entire Ryukyu Islands, echoing Sakhalin Island from a distance, and attacking Japan from the south to the north. In the southwest, we can also go sightseeing casually in the beautiful southern Tibet.

In short, if we had the territory of the Qing Dynasty, today's China would at least not be so crowded, its economy would be more developed, its people's lives would be happier, its military strength would be no less than that of the old United States, and Japan would not dare to expect anything again. All Southeast Asian countries would have to stay quiet, and India would not dare to claim the McMahon Line. Russia and the old United States should also weigh it. China is a veritable superpower.
