How to describe how big Beijing is?

Looking at the panoramic view of Beijing, the extended version can be displayed on the computer, covering the whole screen; Outside the Sixth Ring Road is a mountain, but it is also the boundary of Beijing.

Let's stand in the center of the Forbidden City. The Forbidden City is the axis. We all know the ancient feudal society. Of course, some people pay attention to everything and have a symmetrical aesthetic feeling. Therefore, the central axis of the Forbidden City covers an area of about 720,000. This number may be in everyone's heart. Usually we all know Chaoyang District, Haidian District and Sanlitun, where the youngest stars come and go. Take Haidian District as an example. Haidian District only accounts for 20% of Beijing's area, which is equivalent to a Taipei city. No, it's bigger than Taipei and much bigger than Hong Kong. It's a corner of Beijing. More precisely, a town in Haidian District can be compared with Singapore. This is from a Haidian district in Beijing to describe how big it is. You can understand.

We all know that taking the bus is really troublesome. It takes an hour or two to get there. So it can be said that you may have traveled from the border of France to Germany by car for an hour, and then go to neighboring countries. You may have come to Poland from Germany, but what is Beijing like? You start from Chaoyang District by car. After an hour, you will find that you are still in Chaoyang District. In another hour, maybe you can't even get on the viaduct, and you are still in Chaoyang District.

From Korea to Japan, it can be tested at the same time. You may have walked from one end of Beijing to the other before two or three round trips.

From the number of subways, we can see how big Beijing is, and from the population distribution, we can also see how big Beijing is, and its environmental carrying capacity is also very strong, not to mention the carrying capacity of population and environment.
